Systems and Methods for Infrared Detection
First Claim
1. A fluorescence detection system, comprising:
- a light source for coupling with a mobile device; and
software, comprising machine readable instructions loadable into memory of the mobile device and executable by a processor of the mobile device, capable of;
activating the light source in coordination with capturing one or more images using a camera of the mobile device;
analyzing an image captured with the light source on with an image captured with the light source off, to detect a shift of intensity within a predetermined color range within the images; and
identifying and authenticating an object by measuring the intensity shift within the images.
