测量调制传递函数自动聚焦聚焦评价函数搜索算法 measurement modulation transfer function auto-focusing sharpness function search algorithm

摘要

调制传递函数(MTF)是评价光学系统成像质量的重要指标。根据光学传递函数测量的理论基础，以狭缝、刀口作为目标物，搭建了一套适用于工业用光学镜头的调制传递函数(MTF)测量、成本低、结构简单、精度高、稳定性好的测量光路，并根据光路特点编译了相关测量软件。测量软件根据自动聚焦的基本原理进行了自动调焦的开发，在兼顾效率和精度的前提下，分别采用爬山法和传统方法作为粗调焦和细调焦的调焦搜索算法，并根据不同物镜的成像特点采取不同聚焦函数进行聚焦判定。通过实验显示，该MTF快速检测系统具有良好的稳定性。

Abstract

Modulation transfer function (MTF) is an important imaging quality indicator of optical system. On the basis of MTF testing theories, knife edge and slit as testing targets, a testing system which has low cost, simple structure, but high precision and high stability is developed to evaluating MTF of industrial lens. Besides, a correlative testing software is built according to the above. This testing software basing on the principles of the automatic focusing, and giving consideration to efficiency and precision, includes an automatic focusing system which rough focusing uses the method of mountain climbing as search algorithm, and which elaborate focusing uses the traditional method as search algorithm. In addition, different focusing evaluation functions are used in sharpness evaluation according to the trait of objective. Experimental data indicates this MTF fast testing system has high stability.
