Hyperacuity From Pre-Blurred Sampling Of A Multi-Aperture Visual Sensor

US Patent:
8569680, Oct 29, 2013
Filed:
Dec 21, 2010
Appl. No.:
12/975139
Inventors:
Geoffrey P. Luke - Austin TX, US
Cameron H. G. Wright - Laramie WY, US
Steven F. Barrett - Laramie WY, US
Assignee:
University of Wyoming - Laramie WY
International Classification:
G01B 11/14
US Classification:
250221, 356623
Abstract:
A multi-aperture passive light sensor and method for detecting motion and edges of an object are described. The sensor may include at least two focusing lenses mounted on a spherical surface for focusing light from the object into the ends of optical fibers, the optical axis for each lens diverging at an angle from that of adjacent lenses depending on the intended application. Each lens is located closer to the end of its associated optical fiber, which is disposed coaxially to the optical axis of the lens, than the natural focal plane of the lens, thereby blurring the light received from the object. Light exiting the fibers is detected by photosensors located at the opposite end of each optical fiber, and voltage differences between the voltages generated in response to the light intensity impinging on the photosensors are used to detect motion and edges of the object.

Cooperative Optical-Imaging Sensor Array

US Patent:
2013020, Aug 15, 2013
Filed:
Dec 31, 2012
Appl. No.:
13/732012
Inventors:
Steven F. Barrett - Laramie WY, US
Michael J. Wilcox - Colorado Springs CO, US
David F. Cox - Tucson AZ, US
International Classification:
H04N 5/232
US Classification:
348169
Abstract:
An apparatus and method for providing image primitives, such as edge polarity, edge magnitude, edge orientation, and edge displacement, and derivatives thereof, for an object are described. The data are obtained substantially simultaneously and processed in parallel such that multiple objects can be distinguished from one another in real time.
