Compensating scheme for the LCoS projection system which uses formal double refraction type polarized light bimusupuritsuta

摘要

The LCoS projection system, 2 axial compensating element and, formal double refraction type polarized light bimusupuritsuta which it possesses (PBS) offers between the output irregularity port and the optical modulation panel and the output irregularity port and the optical modulation panel. Regarding 1 execution forms, 2 axial compensating element is the board of 2 axes. Regarding another execution form, 2 axial compensating element, includes with the board and 2 axial trim retarder of 1 axes. Contrast efficiency improves with the utilization of 2 axial compensating element. Selective figure Figure 6A
