256 × 256, 30 µm LWIR HgCdTe SI
Raytheon Vision Systems has developed HgCdTe-on-Si detector arrays, to provide large format FPAs at lower costs. High-quality HgCdTe-on-Si FPAs are available in both LWIR and MWIR materials.

640 × 480, 20 µm VOx Microbolometer
The 640 × 480, 20 micron VOx micro bolometer provides high resolution imagery.

IR Missile Warning Sensor
Raytheon Vision Systems' 256 × 256 InSb, 30 µm pitch MWS sensor with a 106 degree FOV provides warning against MANPADs and A/A threats for airborne platforms.

LWIR Quad Wire Grid Polarimeter
LWIR staring arrays with a quad wire grid design can be used to identify materials and to discriminate samples from a cluttered background. Several FPAs have been built at RVS, each with exceedingly higher extinction ratios. The polarization metal grid was applied to the photon incident surface of a 256 × 256 format LWIR FPA with 30 µm pitch, with each quadrant polarization grid patterned over a 2 × 2 set of pixels. FPAs have been integrated into a field camera and images of polarized materials taken. The live video simultaneously displays Total intensity (S0), Linear Polarization (S1 and S2) and Degree of Linear Polarization (DOLP).

Multi-band Image Fusion
This is a simultaneous acquisition of a 1280 × 1024 SWIR camera and a 640 × 480 LWIR camera on a dark night outside Raytheon's Goleta facility. Each band identifies different features in the scene: SWIR has higher resolution and can see through the window of the vehicle while LWIR picks up temperature and emissivity contrasts such as the cold piece of foil and warm rocks in the foreground. The SWIR camera uses InGaAs detectors sensing radiation from 0.85 to 1.67 µm operating at 280 K while the LWIR camera uses VOx microbolometer detectors sensing 8-14 µm radiation operating at room temperature. Both cameras are running at a 30 Hz frame rate.

640 × 480, 25 µm VOx Microbolometer
This unit provides a wide field of view for airborne and missile platforms.

Uncooled HgCdTe SWIR
This video was shot in a darkened conference room with a camera containing a SWIR HgCdTe 1280 × 1024 focal plane. The detector senses 0.85 to 1.7 µm radiation. The coffee pot on the table contains water but looks black in this SWIR band due to its low reflectivity. In contrast, hair and most fibers are highly reflective and appear bright. The camera is running at a 30 Hz frame rate.
