ABSTRACT:
A radiation detector (1) includes a multi-layered substrate (2,10) having a first major surface, which is a radiation receiving surface, and a second major surface disposed opposite to the first major surface. A first detector is formed adjacent to the first major surface, the first detector being responsive to a wavelength or wavelengths of electromagnetic radiation in the range of approximately 0.3 micrometers (near-UV) to approximately 1.2 micrometers (near-IR). A second detector is formed adjacent to the second major surface of the multi-layered substrate, the second detector being responsive to a wavelength or wavelengths of electromagnetic radiation in the range of approximately one micrometer to approximately twenty micrometers (SWIR to VLWIR). In a presently preferred embodiment the second detector is simultaneously responsive to IR radiation within two distinct spectral bands.
