Abstract
The conducting mesh are used in many infrared-imaging windows, it can provides anti-frost, anti-fog, or electromagnetic wave attenuation functions. In this paper, the influence of conducting mesh for infrared optical system discussed base on Fourier optics principle. The performance evaluation for image including optical system transmission, modulation transfer function and point spread function. Through the mesh transmission function of Fourier transform calculate and analysis, then show the light intensity distribution behind mesh. Given and calculate per rectangular pupil hole function of the mesh, to discuss value changes of Modulation Transfer Function with mesh. So the conducting mesh parameter design and optimize could according to these analysis results. In same time, this paper put forward an example of the mesh design parameters.
