A system and method of providing a periodic trajectory scan path for a laser beam across a photoconductive surface in a laser printer. A preferred embodiment of the periodic trajectory for a system with a two-axis deflector includes a multiple-frequency omega wave trajectory for providing a substantially rectangular grid of available dot locations for selective laser beam pulsing. As such, a plurality of generally linear rows of dots are completed in a single scan pass of the laser beam across the surface. The periodic trajectory is provided by deflecting the laser beam with an optical beam deflector, such as an electro-optic deflector, placed between the laser and the rotating polygon scanning mirror. A preferred embodiment of the beam deflector includes a folded optical path.

A storage device including many field emitters in close proximity to a storage medium, and a micromover, all in a partial vacuum. Each field emitter can generate an electron beam current. The storage medium has many storage areas on it, with each field emitter responsible for a number of storage areas. Also, each storage area can be in a number of different states to represent the information stored in that area. In storing information to the storage device, the power density of an electron beam current is increased to change the state of the storage area bombarded by the electron beam current. In reading information from the device, the power density of the electron beam current is reduced to generate a signal current from the storage area bombarded by the electron beam current. During reading, the power density is selected to be low enough so that no writing occurs. The magnitude of the signal current depends on the state of the storage area.

A double-pass projection display system with separate polarizers and analyzers. One embodiment of the invention includes an input polarizer, a color separation/recombination device, and a number of image producing sections. The input polarizer receives unpolarized white light and polarizes this light. The color separation/recombination device receives the polarized white light and separates this light into a number of component color bands. The color separation/recombination device then supplies a component color band to each image producing sections. Each section includes a spatial light modulator and an output analyzer. The spatial light modulator modulates the color band that the image producing section receives from the color separation/recombination device. The output analyzer then (1) discards the light, in the modulated band, that has a first polarization state, and (2) directs the light, in the modulated band, that has a second polarization state to the color separation/recombination device. The color separation/recombination device then produces a single color light by combining the component color bands that it receives from the output analyzers of the image producing sections.

A portable entertainment media storage module allows an individual to capture one or more entertainment media into the module for later retrieval and consumption. The module includes a high capacity atomic resolution memory device and a communication interface. The memory device is capable of storing one or more packets of entertainment media while the communication interface facilitates reading from and writing to the memory device. In one example embodiment, an individual can capture a packet of entertainment media, such as movie, book, or music CD, from an information library and store that entertainment packet in the module for later consumption using a media player (e.g., CD player, notebook computer, etc.). In one embodiment, the memory device includes an atomic resolution storage device, which is subminiature in size, allowing it to be contained within a small housing such as a pendant, has low power requirements, and provides for non-volatile storage of large amounts of data, including video.

A miniature rotary actuator optical head assembly incorporating data and servo detecting elements mounted inside a source/detector module, which is located on the rotary actuator arm adjacent to the pivot point of the rotary actuator arm. The miniature rotary actuator optical head also includes a miniature focus motor which supports a fold mirror and an objective lens and repositions the fold mirror and objective lens simultaneously whenever a focus error is received. The focus motor can be actuated by a magnetic bias field that originates external to the rotary actuator arm, particularly the magnetic bias field generated for magneto-optical recordation. The optical assembly may also include two stage tracking by mounting the light source on a pair of lateral movement flexures and supplying a fine tracking error signal to actuate the movement of the light source.

A distance measuring device capable of being used in microscopes or other optical systems. Embodiments of the invention employ one or more scanning mirrors to scan a reference beam over a target to be inspected. The reference beam is returned and detected by a photodetector. The reference beam may be created by using a knife-edge element which allows the outgoing reference beam and incoming reference beam to follow the same path so that the apparent motion of the spot on the target surface is not detected by the photodetector. The photodetector generates an electronic signal corresponding to the displacement of the target away from the ideal focal point. The electronic signal may be used to drive a servomechanism to displace either the target or the microscope objective lens to bring the target in focus.

Disclosed are various systems and methods for generating a data signal. In one embodiment, a system is provided that comprises a laser with a gain medium, the laser being configured to emit optical power. The laser is further configured to receive an external optical feedback optically coupled into the gain medium from an optical medium. The external optical feedback is modulated by data embodied in the optical medium. A circuit generates the data signal corresponding to the data based upon a variation in the optical output power of the laser due to the external optical feedback directed into the gain medium of the laser.
