Abstract

A novel depolarizer composed of two quartz sedges is presented. The depolarization mechanism of this depolarizer lies in the double effects of integration over both frequency and space domain. The conditions of the depolarizer for effect depolarization are concluded: (1) the slope of retardance should be large enough; (2) retardance of the depolarizer should be large enough; (3) the angle between optical axes of two crystals should be 45 degrees. Furthermore, the image characteristics of the depolarizer is analyzed and image tripling is demonstrated. The experiment results show that our theoretical analysis is responsible. This depolarizer can be applied in many fields such as astronomy, remote sensor and spectroscopy.
