| 摘 要： | 利用空间光调制器与CCD摄像机,取代传统的光刻掩膜板及白屏,构建成新型光衍射与干涉定量实验系统,将PC机软件绘制的狭缝小孔等衍射图案传输至空间光调制器,用CCD接收其远场衍射和干涉图样,再用PC机处理图像,做定量分析.可验证狭缝和圆孔衍射公式；对形状和空间关系复杂的异形孔,也可方便地实现衍射干涉图样的观察存储与测算.

| Abstract: | Using the spatial light modulator(SLM) and CCD camera to substitute the traditional lithographic masks and white screens,a novel quantitative diffractive and interferential optics experimental system is developed.Slits,apertures and other patterns generated by plotting software of personal computer are sent to the SLM,their far field diffractive and interferential images are acquired by CCD camera,which are then processed and analyzed quantitatively by personal computer.Slits and apertures' diffraction form... |
