Modeling and Simulations of Retina-Like Three-Dimensional Computational Ghost Imaging

Abstract

A retina-like 3-D (three-dimensional) computational ghost imaging (R-3DCGI) is proposed to obtain high resolution while maintaining high imaging efficiency. R-3DCGI models are developed, and corresponding simulations are conducted to verify and evaluate the accuracy and features of the R-3DCGI. Results show that the models obtain rotation and scaling invariances and compress redundant information, thereby improving imaging efficiency over the traditional computational ghost imaging. The relationships between parameters of the retina-like models and signal-noise ratio are discussed to optimize the retina-like structures in various applications.
