Abstract
Digital television frame store devices and software packages have made it possible to obtain images directly from electron microscopes, photographic prints and transparencies in real time and obtain the power spectrum (optical diffraction pattern) and filtered image of various electron micrographs. Enhancements have been added to the Fourier analysis program package which include the use of offset filter functions and the computation of high resolution electron microscope images by including the microscope lens aberration phase shifts and illumination conditions. Because of the use of the frame store and a large mainframe computer, it is possible to have several orders of magnitude gain in image computational speed which makes real-time interactive computations possible.
