Abstract
En 中文
This paper proposes a method for identifying optical component misalignments based on relative ray vector (RRV) observation. Firstly, the RRV is calculated from the gradient direction of the wavefront. Through ray tracing, the model between the RRV and misaligned optical systems can be established. The optimization objective is to minimize the angle error between the theoretical and observed RRV. Using the error backpropagation method, the misalignment parameters of each lens surface can be optimized layer by layer. And then, calculate the lens’s misalignment parameters. Simulation and experiment verified the high performance of this method in dealing with large initial misalignment.
