| Abstract: | Based on geometric theory,diffractive optical eleme nt s applied to shape laser beams is designed,the phase expression of the diffract ive optical elements is deduced.As an example,DOE shaping input Gaussian beam i nto the square frame shape is designed.The calculation results are satisfactory by means of computer simulation.At the same time,experimental results prove the property of the design method,theoretical deduction and program design and the a ccuracy of the design method. |
