Abstract
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.
