引言光学系统成象质量的评价一直是应用光学领域中众所瞩目的问题。人们不断地探索,力图找到一种全面、可靠的评价方法。基于傅里叶变换和线性系统理论上发展起来的光学传递函数OTF(Optical Transfer Func(?)ion)方法,是迄今为止最充分、最全面的评价象质的方法。由于线性系统理论和傅里叶分析在光学领域中的应用取得的巨大成功,人们引入调制传递函数MTF(Modulation Transfer
Introduction The evaluation of the imaging quality of optical systems has always been a subject of considerable attention in the field of applied optics. People continue to explore, trying to find a comprehensive and reliable evaluation method. The Optical Transfer Func (?) Ion (OTF) method developed based on Fourier transform and linear system theory is by far the most complete and comprehensive method for evaluating image quality. Due to the great success of the linear system theory and Fourier analysis in the field of optics, people have introduced the Modulation Transfer Function (MTF)
