We report on the development and
characterization of a field-portable hyperspectral
imager designed to collect 128-band image cubes
simultaneously in both the 4-5.25 \mu m (mid wave
infrared, MWIR) and 8-10.5 \mu m (long wave infrared,
LWIR) bands for detection of target as well as
chemical/biological agents. The imager uses a
specially designed diffractive optics Ge lens with a
cooled dual-band 320..240 HgCdTe focal plane array.
This lens performs both imaging and dispersive
functions. The imager collects a single-color full scene
image with a narrow band in the LWIR (e.g., at 8 ..m)
using the first order diffraction and corresponding
single-color image in the MWIR (4 ..m in this case)
using the second order diffraction at the same time.
Images at different wavelengths are obtained by
moving the lens along its optical axis to focus the
corresponding wavelengths. Here we will discuss the
imager and present field test data and result
