Publication number: 20210010935Abstract: Embodiments of this invention relate generally to detection systems and a method for chemical substance detection using UV fluorescence, specular reflectance, and artificial intelligence. In one example, a handheld detection system comprises single or multiple excitation light sources at discrete wavelengths operating in an ultraviolet portion of an electromagnetic spectrum. The single or multiple excitation light sources are operated intermittently, either all in concert or individually, at a frequency of about 100 Hz to 1000 Hz. Multiple detectors are configured as channels to operate at discrete wavelengths to detect a multiplicity of emissions produced by the excitation energy. A multi-channel electronic or software-implemented detector is synchronized in both phase and frequency with the excitation light sources so that a signal of interest is detected in the multiplicity of emissions.Type: ApplicationFiled: July 6, 2020Publication date: January 14, 2021Applicant: Lightsense Technology, Inc.Inventors: Wade Martin Poteet, Terje A.
