DEVICE AND METHOD FOR OPTICALLY MEASURING THE TRANSMISSION AND DIFFUSION OF OCULAR MEDIA |
摘要 |
<p>An optical device for measuring the transmission and diffusion of a tissue of the front segment of an eye, includes: a light source; an optical collimation system for directing the collimated light beam towards a tissue of the front segment of an eye to be characterized; an optical mire placed on the optical path between the optical collimation system and the tissue; an optical imaging system capable of receiving a light beam transmitted by the mire and the tissue and capable of forming an image of the mire on an image detector; and an image processing system capable of calculating a modulation transfer function for the tissue from an image of the mire through the ocular medium. The optical mire includes a set of alternately light and dark angular sectors radially distributed from a central point. Different image processing methods for extracting a function representing the transmission and diffusion characteristics of the tissue are described.</p> |
