Abstract
A design method of a customizable arbitrary shape structured light mask plate, steps are as follows: based on holographic shaping technology and the current model, the electric field expression of the customizable arbitrary shape structured light beam is obtained, the complex transmittance function of the customizable arbitrary shape structured light beam mask plate is obtained by combining the amplitude, phase and a blazed grating of the light beam, and the mask plate described based on the complex transmittance function is the customizable arbitrary shape structured light mask plate. The mask plate designed by the application can generate a customizable arbitrary shape structured light. The topological charge value of the structured light is controllable, and the structured light with amplitude and phase distribution along any preset track can be generated according to actual requirements. Compared with the previous beam shaping technology, the controllability of the structured light is greatly improved.
