摘要
论述了光电成像系统中广泛使用的分辨率指标及分类,对空间分辨率模拟度量法的原理和测量方法进行了论述和分析。通过研究指出用空间分辨率指标来描述成像系统的质量,具有较好的直观性和归一性。由于单一的空间分辨率测量指标还不可能给出总的图像系统的性能,仅仅基于分辨率指标的图像评估不可能同时保证系统灵敏度设计的技术要求。因此,结合模拟度量法研究光电成像系统的分辨率测量法,给出成像分辨率测量准则。
Index and classification of resolution which are widely used in the photoelectric image system is discussed with analysis of the principle and method of the simulated measurement of spatial resolution. The investigation shows that the index of spatial resolution which describes quality of the image - forming system is more direct and unitary than other methods. However, the single spatial resolution can not show the capability of the whole image system. Besides, the evaluation which it is only based on the index of spatial resolution can not ensure the designed technical requirement of the system sensitivity. There fore,on the basis of the resolution measuring method of the photoelectric image system,a measuring criterion of the imaging resolution is obtained.
