Abstract

Structured illumination microscopy (SIM) is combined with optical image hiding for the first time, to the best of our knowledge. In a linear phase encoding system, secret information might be divulged with the input related to the correct image. In this paper, we propose an optical hiding method in which the concept of SIM is used to create reconstructed host images with an extended spectrum. This method not only improves the security of the image hiding system, but also creates a new perspective for optical image hiding and makes solutions for the defect of the linear phase encoding system.
