光学传递函数是唯一能够把衍射、像差、浙晕及杂散光等各种影响成像质量的因素综合在一起客观评价光学系统成像质量的一个定量指标。随着这一重要技术的推广应用与学术上及工业生产以至消费上的需要,光学传递函数的标准化工作也就显得趋于迫切。光学传递函数的数理基础是傅里叶变换和线性系统理论。为了建立完整的光学传递函数理论基础,需要从它的数理基础出发,统一规定一整套有关的术语、符号和定义,並明确它们的物理意义和数学关系以及与其它成像参数之间的相互关系。按照光学传递函数的理论,成像系统必须满足非相干和等晕条件,但实际应用中对上述条件都有一定程度的偏离。为了 The optical transfer function is the only quantitative index that can objectively evaluate the imaging quality of optical system by combining the various factors affecting the imaging quality such as diffraction, aberration, faint noise and stray light. With the popularization and application of this important technology and the need of academic and industrial production as well as consumption, the standardization of optical transfer function becomes more and more urgent. The mathematical basis of the optical transfer function is Fourier transform and linear system theory. In order to establish a complete theory of optical transfer function, a set of related terms, symbols and definitions needs to be uniformed based on its mathematical basis. Their physical meaning and mathematical relationship as well as their relationship with other imaging parameters should be clarified. According to the theory of optical transfer function, the imaging system must meet the requirements of incoherent and isochronous, but in practical applications there is a certain degree of deviation from the above conditions. in order to
