摘要

In this paper, we present a novel optical design to overcome the over-exposure problem without increasing the specifications of sensors. A spatial light modulator (SLM), which is commonly used for modulating light intensity, is used in our design. In projector systems, SLM is commonly used in conjunction with DMD to modulate the intensity of the projected images. In our design, reverse of this design concept is employed. Intensity modulation is performed on object space, instead of image space. This paper shows two optical designs, one is image system, which image the outside object to SLM. This system has F/8 and Field of View (FOV) 40 degree Hyperfocal image design. The other is a relay image system, which relay the image from SLM to sensor. This relay system has F/4 and magnification of 0.5 times. Our design has successfully reduced over-exposure problems.
