“…An LCD system is connected to a computer, placed under an angle of 45 degrees before another biconvex lens. At the output, a decision can be made concerning the health condition of the analyzed patient [ 99 ]. In another application using a CBJTC (compression-based JTC), Kaewphaluk et al [ 40 ] demonstrated experimentally its robustness to noise in applications of retinal recognition in tele-ophthalmology.…”

Optical correlators are efficient optical systems that have gained a wide range of applications both in image recognition and encryption, due to their special properties that benefit from the optoelectronic setup instead of an all-electronic one. This paper presents, to the best of our knowledge, the most extensive review of optical correlators to date. The main types are overviewed, together with their most frequent applications in the newest contributions, ranging from security uses in cryptosystems, to medical and space applications, femtosecond pulse detection and various other image recognition proposals. The paper also includes a comparison between various optical correlators developed recently, highlighting their advantages and weaknesses, to gain a better perspective towards finding the best solutions in any specific domain where these devices might prove highly efficient and useful.
