Characteristics Of Computer Optical Components

In the application of the electromagnetic wave, according to the different request, people need to alter field's distribution. Many papers suggest, Computer Optics Element (COE) could realize the altering field of light distributing in light wave and microwave band and have wide application future. With the basis of some projects before, we have research on the imaging characteristics of reflecting computer optics element in this paper. And we also improve the software and the design effect.Firstly, this paper gives a detailed analysis of the basic design theory of the COE (Computer Optics Element), and mainly focuses on the scalar diffraction theory. With the basis of these analyses, we research the design software of reflection computer optics element. In this paper, we have research on the characteristics of bandwidth, depth of field and so on to find the best work condition. These conclusions can apply to different element of light wave bands (visible and infrared light) and millimeter wave band. In the course of design element, we usually lack the actual gist to choose some parameters, for example, how to decide the iterative times. When we choose iterative times as one appropriate value, the result begins to converge. This conclusion is very important to the design of element and it can largely improve the efficiency of the design of element.We choose an advanced computer language-FORTRAN 90 which is popular in science calculation and the exploitation environment is CVF 6.6. This paper optimizes the software from software environment and compiling efficiency, analyzing the performance of programs, call on array in effect.The choosing of sampling spots has close relationship with the design effect of optics elements. So, we improve the design software and increase the sampling spots to discuss the relationship of sampling spots and the effect of imaging and enhance the precision of calculation. The conclusions in this paper have a conducting value to the further research on COE in the future.
