However, the back projection test method has the following problems:
1. the minimum field angle of the lens is required to be 16 °. During normal test, the performance of the lens in 0.3 view field, 0.5 view field and 0.8 view field needs to be monitored, and if the field angle of the lens is 20 degrees, the CCD camera cannot monitor the angles of 6 degrees and 10 degrees corresponding to the layout of the 0.3 view field and the 0.5 view field.
