Abstract

Optical elements cannot be perfectly placed in an optical measurement system due to various errors, for instance, errors in lens positions, tilting angles, etc. In this study, an algorithm is proposed to identify these installation errors. A spinning mirror is used to produce many different beam paths so that many measurements can be taken. A simulation is conducted, and it is found that the errors are identified within a few iterations. A more accurate measurement is possible if the errors are compensated.
