【摘要】 斩波器是红外探测系统、激光雷达系统等的重要组成器件,传递函数可以用来描述斩波器的光学传递特性.在对斩波器的光学传递特性进行理论分析的基础上,利用付立叶变换给出了任意形状斩波器的传递函数的数值计算方法,结合Matlab和C语言编制的程序能图像化地将传递函数显示出来,误差分析表明,数值计算结果精度较高.更多还原

【Abstract】 Chopper is an important part of infrared detecting system and laser radar; the transfer function is used to characterize the optical transfer characteristics of chopper.The Fourier transform, Matlab and C programs are used to research and emulate the transfer functions of any form choppers based on the theoretical analysis for the optical transfer characteristic of choppers. The error analysis shows that the precision of numerical analysis results is higher.更多还原
