Patent ID: 8860942

Claim:
A multi-spectral system for detecting a point event comprising: a multi-faceted lens having an incident side and an emergent side, the incident side including a center section and at least two side sections, wherein each side section is coated with a material to filter a particular spectra of radiation from radiation emitted by a point event and received at the incident side of the multi-faceted lens; a focusing lens disposed on an optical axis extending from the emergent side of the multi-faceted lens to focus the filtered radiation emerging from the emergent side of the multi-faceted lens onto a focal plane; a detector positioned at the focal plane and configured to detect the filtered emerging focused radiation; and a control unit including: a processing system; a memory; and processing software resident in the memory, wherein the control unit is connected to and controls the detector to sample the filtered emerging focused radiation in a detection region at a prescribed frame rate to create a spectral diagram of the point event for each frame.
