Calculation of the Arbitrarily Complex Shape Optical Receiver's Aperture Averaging Function by the Two-dimensional Matrix Mapping Method

Authors: Changqi Yang

A method for calculating the arbitrarily complex shape optical receiver’s aperture averaging function is proposed in this paper. In this method, the mathematical shape of the optical receiver is mapped into a two-dimensional n*n matrix. The calculation of the aperture averaging function is transformed into the mathematical operation between two two-dimensional matrices. To verify this method, the Cassegrain telescope's aperture averaging function is calculated by mapping to a 300*300 matrix and compared with the theoretical results. The comparison results show that the error of the aperture averaging function calculated by this method is very small. This method can be trusted to calculate the arbitrarily complex shape optical receiver's aperture averaging function.
