摘　　要：提出一种利用空间光调制器对物方光线进行调制并多次曝光的方法来获取HDR图像.讨论了该方法的原理,并根据原理搭建实验装置进行了实验.实验装置中以LCOS作为空间光调制器,以CMOS作为成像传感器,通过多次曝光获得系列图像,利用图像合成算法生成HDR图像.该方法具有实时性好、扩展性强、成本较低等优点.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.
