METHOD computer registration image signal interferogram

摘要

An image computer recording interferograms, consisting in the fact that the television camera (TV camera), the light flux from the interference pattern of the controlled object is projected on the instrument matrix target charge-coupled device (CCD), forcibly implemented in the photodetector "long" and "short" the accumulation of information charge in adjacent frames (half frames) is formed at the photodetector output multiplex image signal, a video signal is recorded in computer memory, characterized in that the output form eotelekamery form a multiplexed TV signal that is broadcast to the input videokompyutera and video demultiplexing is performed in a computer by executing therein delaying the input multiplex television signal per frame (half-frame) and implementing a weighted summation of the direct and delayed video signals due to the addition of the direct video signal from a single weighting factor K and the delayed video signal by a factor K, selected from the inequality 0 K 1, and recorded in complete optimization ideosignala by selection with remote computer duration "short" exposure photodetector camera.
