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 formulas can be proved by this method.The diffractive and interferential images of abnormal-shaped apertures which are complex distributed may also be observed,stored, measured and analyzed conveniently.

Key words: spatial light modulator（SLM）, charge-coupled device（CCD）, diffraction, interference, experiment
