Portable system for detecting skin abnormalities

摘要

A lightweight hand-held skin abnormality detection system (5) includes a source of excitation light that causes tissue (12) under examination to produce fluorescence light. The fluorescence light produced along with the beam of reference light is provided to a beam splitter (13) which divides the fluorescence light and the reference light into separate optical channels (14, 15). Each optical channel produces an image of the tissue under examination. A passive optical combiner (16) superimposes the image produced by each optical channel for viewing by a user.
