In the laser homogenization experiment, there is a difference between the output from the pre-design and the output from the actual experiment. This is because, apart from the design mistake, the mistake of some lens placement during the lens assembly process greatly affects the final result. Unless there is a way to automate the alignment of all the lenses from the beginning, the only way to find and fix these errors is to re-arrange all the lenses. In this paper, we propose a new error verification method. To accomplish this, we first store all the output that can occur due to the change of the lens arrangement during the simulation process, and then use the machine learning to connect the relationship between the output images obtained from the actual experiment and the previously obtained data.
