摘要： A method for determining a localization parameter of an object includes generating a plurality of estimates of a first frequency-domain amplitude of a baseband signal from the object, each estimate corresponding one of a plurality of temporal segments of the baseband signal. The method also includes determining the first frequency-domain amplitude as most common value of the plurality of estimates, and determining the localization parameter therefrom. A localization system includes a memory and a microprocessor. The memory stores instructions and is configured to store a baseband signal having a temporal frequency component and a corresponding first frequency-domain amplitude. The microprocessor is adapted to execute the instructions to: (i) generate a plurality of estimates of the first frequency-domain amplitude each corresponding to a respective one of a plurality of temporal segments of the baseband signal, and (ii) determine the first frequency-domain amplitude as the most common value of the estimates.

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： In an embodiment, a guidance system determines a location parameter of an object, and includes: at least one oscillating element located at the object for emitting modulated optical radiation; at least two mutually distinct signal-modifying electro-optical sensors, each of the electro-optical sensors having a detector and a demodulator for generating a demodulated electrical signal in response to detection of at least a portion of the modulated optical radiation; and a processor for determining the location parameter from the demodulated electrical signals. In another embodiment, a guidance system has aberration-corrected imaging and includes: a plurality of electro-optical sensors sharing a field of view and mutually distinctly providing a respective plurality of altered images therefrom; and an image generator module for linearly and non-linearly processing spatial frequency properties of the plurality of altered images to synthesize an aberration-corrected image for the imaging system.
