摘要
三次位相的波前编码位相板是一种非旋转对称光学元件。对于其面形及整个元件的检测,虽然目前通用的方式还是采用轮廓仪的接触式测量,但采用非接触式的干涉测量,具有快速、简洁、可避免待测元件的面形不受损伤等优点。非接触式的测量方法,可以采用计算全息图进行零位补偿,但计算全息图的制作价格相对较高。我们根据三次位相波前编码板的面形特点,得到一种新型的零位补偿方式,并给出了设计实例,并进行了实验验证,该补偿器全部由球面镜组成,易于加工,且成本较低。
This cubic wavefront coding phase plate is an asymmetrical surface.Up to now,its main testing method in the industry is using the contact profiler.But non-contact testing method has more virtues,for example,simple,swift,unharmful to the surface under test.Non-contact testing method can use computer-generated hologram（CGH） as null lens,but the CGH manufacture cost is comparatively expensive.We gave a new manner of null lens to test the cubic surface according to the surface characteristic of the cubic wavefront coding phase plate.We described a design of the null lens and made some experiments.The null lens consists of two spherical lenses which are easy to be manufactured at a low price.
