为了测试非球面,提出了一种改进的计算机合成全息图,这种全息图称为倾斜条纹全息图。这种全息图的特点在于倾斜条纹。可通过计算被测透镜的波前偏差来得到每个条纹的倾斜角度。本文分析了与计算机合成全息图有关的一些问题,并通过实验验证了倾斜条纹全息图优越于普通全息图。 In order to test aspheric surfaces, an improved synthetic computer-generated hologram is proposed, which is called oblique stripe hologram. This hologram is characterized by oblique stripes. The tilt angle of each stripe can be obtained by calculating the wavefront deviation of the lens under test. In this paper, some problems related to the computer synthesis of holograms are analyzed, and the experimental results show that the oblique stripe hologram is superior to the ordinary hologram.
