Abstract
Methods and systems for performing a biometric measurement on an individual are disclosed. A containment film is disposed between a skin site of the individual and a platen. Light is directed through the containment film to the skin site to illuminate the skin site under multiple distinct optical conditions. Light scattered from the skin site is received for the multiple optical conditions. A multispectral image of the skin site is derived from the received light. A biometric function is performed with the derived multispectral image.
