Abstract : The microcomputer controlled image processor receives and interference pattern of samples of pairs of transmitted laser beams from a charge couple device (CCD) camera. The present invention then calculates an optical path difference between each pair of beams using: an analog amplifier, an analog-to-digital (A/D) converter, a multiple accumulator controller, a programmable read-only-memory (PROM), a microcomputer, and a random access memory (RAM). The analog amplifier and A/D converter amplify and convert to digital the interference pattern received from the CCD camera. The multiple accumulator controller (MAC) receives the digital camera signal from the A/D converter, and adds correction factors for the nonlinearities in the CCD camera. The PROM stores these correction factors, and supplies them to the multiple accumulator controller when needed. The random access memory receives and stores the corrected data from the multiple accumulator controller, and supplies the data to the microcomputer.
