NEAR INFRARED IMAGING USING LASER ARRAYS WITH DISTRIBUTED BRAGG REFLECTORS

摘要

A smart phone or tablet includes laser diodes, at least some of which may be pulsed and generate near-infrared light and include Bragg reflectors to direct light to tissue/skin. An array of laser diodes generates near-infrared light and has an assembly in front of the array that forms the light into a plurality of spots on the tissue/skin. A receiver includes detectors that receive light reflected from the tissue/skin. An infrared camera receives light reflected from the tissue/skin and generates data based on the received light. The smart phone or tablet is configured to generate a two-dimensional or three-dimensional image using at least part of the data from the infrared camera.
