Abstract
An optical processing system based on noncoherent light processing employs both geometrical and diffraction optical systems. One portion of the optical system performs a subtraction operation of the image from itself where one of the subtracted images is relatively defocused and one is delayed in time from the other. The subtracted image is edge-enhanced and then applied to a spatial filter employing an interferometer in which spatial filters are contained in the interferometer iris plates. Additional spatial filtering is performed on the interference image and the processed image is displayed in an appropriate display which can selectively view the processed image, the unprocessed image or combinations of the two. Light storage elements are employed for storing the processed images in appropriate buffers over a given length of time. The buffers are read out by a flashlamp. Suitable shutters are closed during the readout process.
