The instrumentation for measuring infrared polarization signatures has seen significant advancement over the last decade.
Previous work has shown the value of polarimetric imagery for a variety of target detection scenarios including detection
of manmade targets in clutter and detection of ground and maritime targets while recent work has shown improvements in
contrast for aircraft detection and biometric markers. These data collection activities have generally used laboratory or
prototype systems with limitations on the allowable amount of target motion or the sensor platform and usually require an
attached computer for data acquisition and processing. Still, performance and sensitivity have been steadily getting better
while size, weight, and power requirements have been getting smaller enabling polarimetric imaging for a greater or real
In this paper, we describe Pyxis®, a microbolometer based imaging polarimeter that produces live polarimetric video of
conventional, polarimetric, and fused image products. A polarization microgrid array integrated in the optical system
captures all polarization states simultaneously and makes the system immune to motion artifacts of either the sensor or the
scene. The system is battery operated, rugged, and weighs about a quarter pound, and can be helmet mounted or handheld.
On board processing of polarization and fused image products enable the operator to see polarimetric signatures in real
time. Both analog and digital outputs are possible with sensor control available through a tablet interface. A top level
description of Pyxis® is given followed by performance characteristics and representative data.
