Combined total-internal-reflectance and tissue imaging systems and methods

Abstract From the Canadian patent

Methods and systems are provided for combining total-internal-reflectance and tissue imaging to perform biometric functions. The system may include an illumination source, a platen, a light detector an optical train, and a , computational unit. The platen is disposed to make contact with a skin site of an individual. The optical train is disposed to provide optical paths between the illumination source and the platen and between the platen and the light , detector. The combination of the illumination source and optical train provides illumination to the platen under multispectral conditions. The computational unit is interfaced with the light detector and has instructions to generate …
