Abstract

Deep aspherical surfaces are often detected using computer-generated hologram, this method testing the surface shape with high accuracy, but it is necessary to design a unique computer-generated hologram for a certain asphere to achieve the detection, in order to deal with this problem, this paper proposes to utilize the multifocal lens for the detection of the depth aspherical surface shape. First, the key parameters of the multifocal lens are calculated, second, the simulation experiments of the multifocal lens for detecting aspherical surface are carried out, finally, the surface shape detection experiments of aspherical surface are carried out with the multifocal lens. The depth aspherical surface shape detection method proposed in this paper can effectively complete the depth aspherical surface shape detection without limitation of individual compensation.
