Method of HDR image acquirement based on space light modulator

A new acquirement method is offered, in which a space light modulator is used to acquire images with different exposure, and then a HDR image is made with these images. The principle of this method is discussed, and experiment system including LCOS and CMOS is built up to acquire a series of images with different exposure. HDR image is composed with synthesize arithmetic. The system is cheap and easy to extend.link_to_subscribed_fulltex
