Abstract
A method comprising: providing a device for detecting a biological signature behind a glass surface using non-visible light is provided. A method of emitting one or more pulses of energy at a specific wavelength over a field of illumination towards a target area, filtering out one or more returning wavelengths from the target area, and determining, based on the filtering, if a combination of a fluorescence wavelength and a source wavelength is present, is also provided. An associated system is further provided.
