Modeling and simulation of the retina-like image sensor based on space-variant lens array

A retina-like image sensor based on a space-variant lens array is proposed. First, the mathematical models of the proposed image sensor and its space-variant lens array are developed and verified. Second, the relationships among the parameters of the space-variant lens have been simulated and discussed. Finally, some conclusions are deduced, which will help to result in a retina-like image sensor with the characteristics of high speed, large resolution, high sensitivity, and big planar array, etc.
