Abstract
Devices, methods, systems, and computer-readable media for a multiband detector are described herein. One or more embodiments include a multiband detector designed to detect an emission source including a broadband lens, a broadband detector, and a filter that allows electromagnetic radiation entering the system to be filtered into at least two wavelength bands before contacting the broadband detector wherein one or more wavelength bands are used to determine system functionality and wherein one or more other wavelength bands are used to identify the presence of an emission source having a characteristic particular wavelength or wavelength range.
Claims20
A filter, comprising:
- wavelength bands to allow electromagnetic radiation entering the filter to be filtered into at least two wavelength ranges before contacting a detector to identify a presence of an emission source having a particular wavelength range.
A system for a multiband detector, comprising:
- a filter to allow a first wavelength band of electromagnetic radiation within a mid-wavelength infrared (MWIR) range and a second wavelength band of electromagnetic radiation within a long wavelength infrared (LWIR) range;
- and
- a computing device coupled to a detector to provide detection of an emission source based on received transmitted radiation from the first wavelength band within the MWIR range and a fail safe operation based on the received transmitted radiation from the second wavelength band within the LWIR range.
A system for a multiband detector, comprising:
- a lens to receive radiation from a field of view for an area;
- a filter to receive radiation from the lens, wherein the filter allows a first wavelength band within a mid-wavelength infrared (MWIR) and a second wavelength band within a long wavelength infrared (LWIR) to pass through the filter;
- a broadband detector to receive transmitted wavelengths from the filter;
- and
- a computing device coupled to the broadband detector to determine an existence of obstructions of radiation received by the lens.
