Error Analysis of Optical Alignment Based on Multi-Beam Splitting

Abstract:

Beam splitter is widely applied in many optical systems. The beam splitter is generally composed of many reflective mirrors and beam splitting prisms. The optical components can not reach the theoretical design state during assemble process. It must be solved through optical alignment. The mathematics model of alignment and error analysis for beam splitter are built in this paper. The effect of optical alignment error of beam splitter on optical system could be analyzed with this mathematical model. At the mean time, the mechanical alignment of beam splitter is directed to fast alignment in practical process. One kind of optical communication system is shown as example. The optical transmitting exit is commonly used. The requirement of axis parallelism of sub-systems is very strict. The axis parallelism between sub-systems reaches 5’’ in experiment with this model application.
