ABSTRACT
In this paper, we propose a photon-counting double random phase encryption with merging reconstruction. Double random phase encryption (DRPE) is a simple and secure optical encryption technique using phase random masks. To enhance the security level, a three-dimensional photon counting technique has been applied to DRPE. However, we cannot recognize the original image information in a photon-limited scene. To solve this problem, we propose a merging reconstruction method, which can detect the photons using several reconstruction layers. Through this method, we can obtain a decrypted image of enhanced visual quality. This paper presents a simulation test for the proposed method.
