文章提出了一种用激光照排机来制作消激光散斑光学滤波信息处理实验仪中光栅物的新方法,设计了基于Matlab的光栅调制物的图像处理程序,可以方便地制作45°方向和各种频率的光栅物,实现了45°斜方向光栅调制物的快速、准确、不产生周期畸变的制作。与全息干涉法制作θ调制片相比,该方法制作过程简洁易操作,叠加光栅方便,图案边框套准精确,易于更换图片,可以满足光学信息处理实验的要求。
This paper presents a new method of laser grating machine to produce grating speckle optical filter information processing experimental apparatus of the new method, the design of the grating modulation based on Matlab image processing program can be easily produced 45 ° direction and The frequency of the grating material, to achieve a 45 ° oblique grating grating fast, accurate, does not produce periodic distortion of the production. Compared with holographic interferometry method, the manufacturing process of the method is simple and easy to operate, the grating is convenient to be superimposed, the register of the pattern frame is accurate, and the picture is easy to be replaced so as to meet the requirements of optical information processing experiment.
