Abstract
This paper illustrates a technique to enhance the image resolution of an optical sensor beyond its Rayleigh diffraction limit. Calibration of the optics and suitable signal processing algorithms to solve the image conditions described herein readily provide imagery enhanced beyond the diffraction limit. A practical example is drawn from an optical experiment set up at Pacific-Sierra Research Corporation, using a video monitor and video camera, all under computer control. Calibration data was taken and the equations for enhanced imagery were solved to demonstrate imagery enhanced by a factor of x2 beyond the Rayleigh limit. Further enhancement is possible and appears to be limited only by the signal-to-noise ratio of the image.
