Structural Design Of Joint Transformed Correlator

With the electronic imaging devices and the continuous development of computer technology, optical correlation detector matched filter from the initial development to today's joint transformed correlator. In recent years, the joint transformed correlator rapid development towards real-time, programmable direction. It has high sensitivity, simple equipment, without damage, and many other advantages of an object under test, in the scientific research has been widely used. However, in the past we used opto-electronic hybrid joint transformed correlator larger, complex structure, to its application to the actual combat is still some distance from them. In this paper, the joint transformed correlator small design, so that in the military field has a new application prospects.In this paper, UG, AutoCAD and other computer-aided design software, for small joint transformed correlator parts were structural design, and through spatial filter, collimating beam expander system, adjusted to ensure its accuracy and stability, reached a small, lightweight requirements.In this design, to replace the traditional use of EALCD reproduced hologram optical storage media, will be reset to the CCD records EALCD accurately the location of a hologram with the original reference beam irradiation to reproduce, and the use of the key devices and joint transformed correlator The overall performance was tested on the impact of the output correlation peak intensity was analyzed, and ultimately the purpose of miniaturization.
