| 摘要 |
<p>The invention relates to an optical characterisation method which uses automatically-controlled images comprising a system that is used to display images, a system that is used to capture said images and a system that is used to control the latter two systems and to analyse the information relating to the captured images. The optical element to be examined is positioned such that the light rays from the image-forming system pass through said element or are reflected by same. The analysis of the image(s) registered can be used to obtain one or more of the optical characteristics of the object examined. By controlling the images used, the measurement characteristics (range, sensitivity, speed, etc.) can be adjusted in order to produce the optimum characteristics according to the specific requirements.</p> |
