Optical modeling and simulation method of optical and mechanical system under air disturbance

Abstract

The invention provides an optical modeling and simulation method of optical and mechanical system under air disturbance. It achieves the optical performance assessment within the same software and addresses many problems arising from the calling of multiple application software in the integrated simulation in the past to make the simulation faster and more stable through the development of integrated optical modeling algorithm (the core of which is ray-tracing). For the simulation of air disturbance, the adopted approach is to first discretize it, simulate the air disturbance as the disturbance of each partition surface, and simulate each part of air as the prism of different refractive indexes. This simulation method simulates the complex air fluid as the rigid disturbance of disturbance surface and simplifies the complex issue, which is easy for the actual operation of computer simulation. This method, with simple modeling and simulation operation and low error rate, only need use the integrated optical modeling algorithm programming, and input the parameters of the designed optical and mechanical system and the parameters of divided air surfaces to calculate the disturbance optical sensitivity matrix of the system. During the simulation, it sets the parameters of the module as these disturbance optical sensitivity matrixes to obtain the real-time disturbance optical performance of the system. In addition the method requires low computer hardware configuration, with high applicability and economy.

technical field [0001] The invention belongs to the field of optical modeling and simulation, and relates to the development of an optical modeling tool and an optical model establishment and simulation method under air disturbance. technical background [0002] At present, the design and development of high-precision optical-mechanical systems more need to be carried out with the help of integrated simulation of optics, mechanics, and electricity. The integrated simulation technology uses a simulation software as the core to cooperate with professional software in other fields to carry out synchronous simulation technology by establishing a data interface. However, the communication between different software needs to establish an inter-software protocol, establish a connection, data transmission, terminate the connection and other steps, which will inevitably affect the simulation speed and stability. In the simulation of the optical-mechanical system, Matlab / Simulink is ...

However, due to its complexity (involving issues such as heat convection, heat radiation, fluid diffusion, etc.), it has been puzzling the designer's in-depth understanding of this aspect and the effective development of work.

At present, there is no effective method for simulating air turbulence. The present invention uses air discretization as a breakthrough, and discretizes the air into many prisms with different refractive indices. Effects of Perturbations on the Performance of Opto-Mechanical Systems
