Latest Patents

Champagnat holds a patent for a "Method for designing a passive single-channel imager capable of estimating depth of field." This computer-implemented method involves designing an electro-optical imaging system that estimates the distance of a source. The method utilizes an optical subsystem, a detector subsystem, and a digital image processing subsystem. It includes modeling the propagation of radiation from its source through these subsystems, based on a spatial model of the source. A key aspect of the method is the simultaneous design of the optical subsystem and the digital image processing subsystem, which is based on performance metrics that compare local estimations of distance with actual distances.
