摘要： A coded localization system includes a plurality of optical channels arranged to cooperatively image at least one object onto a plurality of detectors. Each of the channels includes a localization code that is different from any other localization code in other channels, to modify electromagnetic energy passing therethrough. Output digital images from the detectors are processable to determine sub-pixel localization of the object onto the detectors, such that a location of the object is determined more accurately than by detector geometry alone. Another coded localization system includes a plurality of optical channels arranged to cooperatively image partially polarized data onto a plurality of pixels. Each of the channels includes a polarization code that is different from any other polarization code in other channels to uniquely polarize electromagnetic energy passing therethrough. Output digital images from the detectors are processable, to determine a polarization pattern for a user of the system.

摘要： An angular localization system for determining an object's location includes a signal processor and three channels have a respective first, second, and third photodetector. The first channel images a first portion of an optical signal from which the first photodetector generates a first electrical signal. The second channel images a second portion of the optical signal onto a slow-varying optical mask having a strictly monotonic transmissivity along a dimension x. The second photodetector converts the second portion into a second electrical signal. The third channel images a third portion of the optical signal onto a fast-varying optical mask having a spatially-varying transmissivity having a same value at more than one value of x. The third photodetector converts the third portion into a third electrical signal. The signal processor is configured to determine, from each electrical signal, a respective signal amplitude, and determine the location parameter by comparing the signal amplitudes.
