Research on the space-variant image sensor based on optical method

摘要

A novel space-variant image sensor based on optical method is proposed. Firstly, the mathematical models of the proposed image sensor and its non-uniform lens array are developed and verified. Secondly, the relationships among the parameters of the non-uniform lens have been simulated and discussed. Thirdly, experiments are carried out for verifying the characteristic of rotation and scaling invariance of the proposed image sensor. Finally, some conclusions are deduced, which will help to result in a space-variant image sensor with the characteristics of high sensitivity, high speed and big planar array, etc.
