An electronic holographic computer has been developed that generates both time-average and two exposure holographic interferograms. The interferograms are continuously updated at a rate of 30 frames per second and the image quality can be enhanced with both temporal frame averaging and spatial speckle averaging. The results rival the quality of film holography for resolving interference fringes. The electronic image processor allows immediate enhancement of the resultant images as well as flawless, compact digital storage on magnetic media. Details of the algorithms are given and results are discussed. Two applications of the system are also mentioned and sample images are included.
