Development of a multi-spectral imaging system for optical diagnosis of malignant tissues

摘要

A multi-spectral imaging system is presented consisting of a spatially and spectrally uniform light source, an electronically tuneable bandpass filter and a sensitive digital camera. When properly calibrated with a white reference, it can reproducibly grab the reflection spectrum of any accessible tissue surface. After a description of technical challenges, some examples are given for the application in dermatology.
