| Abstract: | Parallel beam splitting technology with variable displacement difference and equal optical path is proposed based on the property of the thick wave plate,and the transmission-type and the reflection-type beam splitters are given. The transmission-type beam splitter consists of the same two thick wave plates and a half wave plate. The reflection-type beam splitter includes a beam splitter, a thick wave plate, a quarter-wave plate and a mirror. The displacement difference can be changed by rotating the thick wave plate. Experimental results agree with the theoretical values. The validity of the parallel beam splitting technology is verified. |
