摘要

"fluorescence filter spectrum compensation". A device provides light incident on oral structures alternately between two states. In the first state, incident light causes the autofluorescence of decay byproducts, and an optical filter between the oral structures and the user's eyes or a visualization device to generate visually distinguishable appearances for this autofluorescence depending on whether the tissue is healthy or diseased. . In the second state, the incident light is of a color composition that generates a substantially "white" spectrum after passing through the filter.
