Abstract

A simple method to evaluate the focal length of concave mirrors is proposed. The inverse ray-tracing approach of the Ronchi test is used in the measurement stage. The theoretical principles are given and a numerical method for ronchigram processing is proposed. The results verify the feasibility of the proposal.
