Abstract:
1. A multi-color infrared (IR) imaging device comprising: a focal plane array for detecting both MWIR and LWIR, said focal plane array having at least a first set of pixels and a second set of pixels defining a pixel group, each of said sets of pixels having a pixel area, said pixel group having a pixel group area; said first set of pixels further comprising a first pixel, a first pixel filter, a first stratum, a first MWIR detector layer and a first LWIR detector layer, said first pixel being coupled to an integrated circuit; said second set of pixels further comprising a second pixel, a second pixel filter, a second stratum, a second MWIR detector layer and a second LWIR detector layer, said second pixel being coupled to said integrated circuit; optics for simultaneously directing said MWIR and said LWIR in focus onto said focal plane array, said MWIR defining an M band, said LWIR defining an L an inhomogeneous filter, comprising said first pixel filter and said second pixel filter, overlaid on the focal plane array so that said M band and said L said first set of pixels generate a first pixel output that includes said L said second set of pixels generate a second pixel output that includes said L a multiple amount of said first set of pixels and said second set of pixels being placed on said focal plane array; and said first pixel outputs and said second pixel outputs generate a radiation map converted into a plurality of electric impulses read by said integrated circuit, said integrated circuit provides a high-resolution color infrared image to a means for display.
