Lidar With Streak-Tube Imaging,Including Hazard Detection In Marine Applications; Related Optics

US Patent:
6836285, Dec 28, 2004
Filed:
Sep 3, 1999
Appl. No.:
09/390487
Inventors:
Stephen C. Lubard - Woodland Hills CA
John W. McLean - Tucson AZ
J. Kent Bowker - Essex MA
Anthony D. Gleckler - Tucson AZ
Assignee:
Arete Associates - Sherman Oaks CA
International Classification:
G01C 308
US Classification:
348 31, 348 81, 356 401
Abstract:
In some aspects of the invention, a LIDAR subsystem or other means at an elevated position emit thin fan-beam light pulses at a shallow angle, and detect reflected portions of the pulses at a like angle; a streak-tube subsystem or other means image successive reflected portions to detect objects, for example near a water craft if the elevated position is on such a craft (e. g. , a mast or high bridge). In some aspects, the imaging means perform the imaging in a way that tightly localizes reflection from a water surface near the objects, to facilitate detecting the objects despite proximity to the surface. Some preferred embodiments apply a correction for energy reduction, or depth errors, near lateral ends of the fan beam; a lenslet array is preferred for applying the correction. Preferably the shallow angle is in a range of approximately one to fifteen degrees, more preferably approximately two to ten degrees, ideally roughly five degrees.

Fingerprint--Acquisition Apparatus For Access Control; Personal Weapon And Other Systems Controlled Thereby

US Patent:
5812252, Sep 22, 1998
Filed:
Jan 31, 1995
Appl. No.:
8/382220
Inventors:
J. Kent Bowker - Essex MA
Stephen C. Lubard - Woodland Hills CA
Assignee:
Arete Associates - Sherman Oaks CA
International Classification:
G06F 704, G06K 974, G01J 104, G02B 606
US Classification:
356 71
Abstract:
At a first end of an optic-fiber prism assembly are fiber terminations to contact a relieved surface, e. g. finger (stabilized by a handgrip). In a region where fiber diameter is essentially constant with longitudinal position, light enters the prism, crosses the fibers and enters individual fibers through their sidewalls, lighting the terminations. To allow crosslighting of the assembly, the fiber-optic numerical aperture (NA) is small: preferably not exceeding one-half. Due to fingerprint etc. detail, fractions of light pass along the fibers; at the assembly second end a detector responds with an electrical-signal array based on the surface relief. The signals are processed to check finger etc. identity and applied to control access to a personal weapon, other equipment, facilities, data, or a money service. FTIR ("frustrated total internal reflection") bright- and dark-field versions have various benefits.

Underwater Imaging In Real Time, Using Substantially Direct Depth-To-Display-Height Lidar Streak Mapping

US Patent:
5467122, Nov 14, 1995
Filed:
Apr 12, 1993
Appl. No.:
8/046335
Inventors:
Kent Bowker - Essex MA
Stephen C. Lubard - Woodland Hills CA
Assignee:
Arete Associates - Sherman Oaks CA
International Classification:
H04N 718
US Classification:
348 31
Abstract:
An imaging system for detecting the contents of a turbid medium, such as water or air, which is at least partially transmissive of light. The system includes a light source for producing a series of discrete fan-shaped pulse beams which are substantially uniform in intensity or have been peaked at the edges of the fan to illuminate sections of the medium, a streak tube with a large photocathode for collecting the maximum amount of light from weak returns, a field-limiting slit disposed in front of the photocathode for removing multiply scattered light, a large aperture optical element for collecting and focusing the reflected portions of the pulse beam on the field-limiting slit and the photocathode, and an array of detectors. A volume display of the medium is generated by translating the transmitter and receiver normal to the longitudinal axis of the pulse beam to illuminate adjacent sections of the medium, and combining the sections to provide a volume display. All, or substantially all, of the light returned from each pulse beam is utilized.

US Patent:
6873716, Mar 29, 2005
Filed:
Nov 4, 1999
Appl. No.:
09/125259
Inventors:
J. Kent Bowker - Essex MA, US
Stephen C. Lubard - Woodland Hills CA, US
John W. McLean - Tucson AZ, US
Assignee:
Areté Associates - Sherman Oaks CA
International Classification:
G06K009/00
US Classification:
382128, 356441, 424 96, 600310
Abstract:
The system images the volume of a turbid medium and detects the contents. The medium can be water or air, or living tissue, or almost any other material which is at least partially light-transmissive. The system includes a light source for producing a series of discrete fan-shaped pulse beams that are substantially uniform in intensity or have been peaked at the edges of the fan to illuminate sections of the medium, a streak tube with a large, thin-slit-shaped photocathode for collecting the maximum amount of light from weak returns, a field-limiting slit disposed in front of the cathode for removing multiply scattered light, a large-aperture optical element for collecting and focusing the reflected portions of the pulse beam on the field-limiting slit and the cathode, and an array of detectors. A volume display of the medium is generated by translating the transmitter and receiver normal to the longitudinal axis of the pulse beam, to illuminate adjacent sections of the medium, and combining the sections to provide a volume display. All, or substantially all, of the light returned from each pulse beam is used.

Lidar With Streak-Tube Imaging, Including Hazard Detection In Marine Applications; Related Optics

US Patent:
7683928, Mar 23, 2010
Filed:
Dec 27, 2004
Appl. No.:
11/023042
Inventors:
Stephen C. Lubard - Woodland Hills CA, US
John W. McLean - Tucson AZ, US
J. Kent Bowker - Essex MA, US
Anthony D. Gleckler - Tucson AZ, US
Assignee:
Arete' Associates - Northridge CA
International Classification:
H04N 7/18, G01P 3/36
US Classification:
348144, 356 285
Abstract:
The system and method relate to detection of objects that are submerged, or partially submerged (e. g. floating), relative to a water surface. One aspect of the invention emits LIDAR fan-beam pulses and analyzes return-pulse portions to determine water-surface orientations and derive submerged-object images corrected for refractive distortion. Another defines simulated images of submerged objects as seen through waves in a water surface, prepares an algorithm for applying a three-dimensional image of the water surface in refractive correction of LIDAR imaging through waves—and also models application of the algorithm to the images, and finally specifies the LIDAR-system optics. Yet another emits nearly horizontal pulses to illuminate small exposed objects at tens of kilometers, detects reflected portions and images successive such portions with a streak-tube subsystem. Still others make special provisions for airborne objects.

Economical Skin-Pattern-Acquisition And Analysis Apparatus For Access Control; Systems Controlled Thereby

US Patent:
5963657, Oct 5, 1999
Filed:
Sep 9, 1996
Appl. No.:
8/709785
Inventors:
J. Kent Bowker - Essex MA
Stephen G. Miller - Great Falls VA
Stephen C. Lubard - Woodland Hills CA
John M. Wartman - Malibu CA
Clive Bolton - Melrose MA
Assignee:
Arete Associates - Sherman Oaks CA
International Classification:
G06K 900
US Classification:
382127
Abstract:
Surface relief of a finger etc. is read using an optical-fiber prism unit, with fiber terminations at one end to contact the surface, and at the other for light passage along fibers from the first. Light enters where NA<0. 5 and fiber diameter is constant with longitudinal position. The device is in a 1. 4-2 L case, with a battery or power input, converter to form a corresponding data array for verifying, digital signal processor to do the verifying, and output to indicate or implement a decision. A video controller (with custom-programmed logic circuit) operates the sensors to develop the data array; an ADC digitizes the array; memory holds an authorized-user skin-pattern template, firmware for the processor, and data used in verifying; an output register holds the decision signal--all on a control, address, and data bus. High-power, radiative elements and a fast high-impedance data reader are on a common board in an isolating layout. The prism unit is cylindrical, held by a cylindrical-section cradle and forming a novel condenser lens to support lights and couple light to the prism.

Noninvasive Polygraph Technology Based On Optical Analysis

US Patent:
7831061, Nov 9, 2010
Filed:
Nov 24, 2008
Appl. No.:
12/313743
Inventors:
Stephen C. Lubard - Woodland Hills CA, US
J. Jerome Holton - Alexandria VA, US
Assignee:
Defense Group, Inc. - Falls Church VA
International Classification:
G06K 9/00
US Classification:
382100
Abstract:
A system and method for unobtrusively and noninvasively subjecting a living subject to tests for the purpose of determining whether that subject is truthful or is under stress, or both. A series of radiation pulses, preferably infrared laser pulses, is directed by a lidar transceiver toward the subject—which returns (e. g. reflects or scatters) the pulses back to the transceiver, which time-resolves that return to segregate and isolate phenomena at, within or in front of the subject's skin. The transceiver is connected to an information processing device capable of determining various physiological characteristics exhibited by the subject in these several regions, respectively. A display associated with the processor visually indicates these physiological characteristics.

Long-Range Uuvs

US Patent:
2013012, May 23, 2013
Filed:
Nov 19, 2011
Appl. No.:
13/373571
Inventors:
STEPHEN C. LUBARD - Woodland Hills CA, US
International Classification:
B63H 21/38, B63G 8/08
US Classification:
114337, 220562
Abstract:
In one aspect, the invention is a vehicle working in ambient-pressure liquid or gas medium; in a second, it is a fuel tank for such craft—usually with a housing and related propulsion; the tank is craft-mounted, at least partly outside all other parts, contacting the medium; and best at least partly pressure compliant; propulsion consumes fuel; drag depends on structure shape, and fuel volume. Shape decreases longitudinally and/or laterally, reducing drag with fuel use; housing is cylindrical, structure annular (outside the housing); drag depends partly on structure radial thickness, in turn on fuel quantity. Pressure may compress fuel against housing. The structure best is made of or has embedded skin-drag reducing material; materials (soaking-replenished) are best low-friction and/or high-compliance; the surface-noise-absorbing (for underwater craft) structure has shape and size reduction some 20 to 80% of like fixed-geometry craft.
