  Optical Security System using Random Gratings for Optical Coding and Multiplexing
  Author(s): Mohammad Sohail*
  
  In the modern age, due to the rapid development of communication techniques, individuals can be secured by the application optical signal processing technology. In this paper, we have proposed a new technique that is using a multiplexing tactic for optical encrypting mechanism to secure the individuals for multiple users. Here in this paper, we are modifying the classical joint transform correlator to provide more security which is easy in implementation. Our proposed technique that is using encoding and decoding procedure provides more security than the previous techniques. In this approach, amplitude random mask was used for encoding as well as decoding procedure but in a holographic format that modulates the input information and enables us to recover the input information from modulated signal which is difficult for other people. For encoding process, we project the spectrum of th.. Read More»
