CODED LOCALIZATION SYSTEMS, METHODS AND APPARATUS

摘要

A coded localization system includes a plurality of optical channels arranged to cooperatively distribute electromagnetic energy from 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. Digital outputs 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 distribute a partially polarized signal 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. Digital outputs from the detectors are processable to determine a polarization pattern.

1. A navigation system for a repositionable object, comprising:
a first optical motion unit having a first plurality of optical channels and configured to capture information from a first portion of a moving scene; a second optical motion unit having a second plurality of optical channels and configured to capture information from a second portion of the moving scene, the second optical motion unit being displaced from the first optical motion unit by a first distance in a first direction; and a processing subsystem configured to determine a two dimensional change in motion of the scene based upon data output from the first and second motion units and the first direction and distance.
