Abstract

A mirror in a static situation can be measured by a laser tracker with its reflector, based on the principle of reflection. Each surface location needs to be measured twice: once for the image point after reflection and again for the same point directly measured. This principle, in comparison with contact measurement, will be presented in this article. High precision can be achieved through this method, which is a promising application if contact measurement is prohibited due to concerns regarding safety, radiation, or other reasons.
