光束的波前调制在光镊、原子捕获、量子信息处理和光学计算等领域有潜在的应用价值。本文利用传统胶片照相技术，通过计算机全息的方法制作了不同的分叉全息光栅。通过这种全息光栅在实验上实现了对高斯光束的波前调制，不仅让学生体验了传统的照相操作过程，而且让学生对波动光学中的相关概念有了深入的认识。

Optical vortices with modulated wave-front have potential applications in the fields of optical tweez-er,atoms trapping,quantum information process and optical computation. In the paper,we purposed an experi-ment to realize the wave-front modulation. In the experiment,the fork-like gratings are manufactured by com-puter generated holographic method in photographic film. Optical vortices with different topological charge can be produced by these holographic gratings in photographic film. The students can enjoy the photographs tak-ing,film developing and wave-front modulating in the experiment.
