Abstract
An apparatus for multi-spectral imaging includes a microbolometer array comprising a two-dimensional array of microbolometer detectors that are configured to respond to energy having a first range of wavelengths comprising a first plurality of spectral bands. The apparatus also includes a wideband window configured to allow energy having a second range of wavelengths to reach the microbolometer array. The second range of wavelengths comprises a second plurality of spectral bands. The apparatus additionally includes optics configured to focus the energy from a scene towards the microbolometer array. The apparatus further includes a processor configured to generate an output based on a response of the microbolometer array to energy having a third range of wavelengths comprising a third plurality of spectral bands. There is substantial overlap between the first, second, and third range of wavelengths and the first, second, and third plurality of spectral bands.
