Abstract

Collimated transillumination is a technique based on the observation that some of photons from a laser beam can traverse an entire tooth, and other tissues in an apparent straight light path and therefore make a shadow of any pathology on the receiver similar to x-rays. To observe the very weak, transmitted, unscattered light rays a special patented system has been developed using collimated, narrow light beams and a highly sensitive, post collimated receiver which rasterscans the entire sample. The image is then transferred to a film. To increase the sensitivity a high resolution mode (HR) has been added.
