P‐111: The Mechanical‐Optical Properties of Wire‐Grid Type Polarizer in Projection Display System

In order to eliminate the thermal issues of the polymer based polarizer and thermal induce birefringence of bulky PBS, the wire‐grid type polarizer is a promising optical component. However, as a part of the imaging optics, mechanical holding may affect the image qualities. In this article, two configurations for using wire‐grid polarization are introduced. The image defects including astigmatism and distortion due to improper mechanical holding are evaluated.
