Abstract:
1. A method of determining wavefront aberrations of an optical signal, for at least one of a targeting, sensor, and imaging system, in order to correct for the wavefront aberrations of the optical signal, the method comprising: forming a first image data from a first rendition of the optical signal; forming a second image data from a second rendition of the optical signal, the second rendition being different than the first rendition; providing the first image data and the second image data to a field programmable gate array (FPGA) system; in the FPGA system, combining the first image data and the second image data using a phase diversity technique; and in the FPGA system, in response to combining of the first image data and the second image data, determining wavefront data representing the wavefront aberrations on the optical signal in order to correct for the wavefront aberrations of the optical signal.
