Paper Abstract

A light imaging system is being developed which can at this time detect and characterize small lesions on the surface and deep inside a tooth or tissue. It depends on the existence of light photons which can fully traverse a tooth in a straight path and therefore can make -- similar to x rays -- a clear shadow of a pathology on the receiver. 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 are rasterscanned over the entire sample. The image can be transferred in analog form to a film or observed after digitization on a 256 grayshade monitor. The light image can be observed in a regular or slower high sensitivity mode.
