ITT Exelis DSNVG Dual Sensor Night Vision Goggle (AN/PSQ-20)

The DSNVGcombines an image intensified (I2) tube and infrared (IR) micro-bolometer into a compact monocular. The DSNVG monocular is approximately the same size as the AN/PVS-14. The two capabilities can be used individually or simultaneously creating a “fused” image standard night vision with thermal overlay, allowing the operator to detect, identify, and engage targets more effectively and efficiently.

An impact resistant polymer housing surrounds simple controls: I² control knob (doubles as gain control and overlay mode switching), thermal control knob (doubles as brightness control and polarity switching) and an IR illuminator On/Off paddle. An I/O port allows it to connect to various other devices.

The DSNVG is powered by four standard AA batteries, housed in a separate battery module. This module can attach directly to the imager for use as a hand-held device, or attaches to the rear bracket of the proprietary helmet mount acting as a counterweight. The DSNVG can be mounted on the MICH/ACH helmet and will provide: flip-up, tilt, fore/aft adjustment; left/right eye use; and quick disconnect from the helmet.

The DSNVG is in production to provide fusion (via optical overlay) of I² and IR imagery, to provide the user with the following benefits:

1. Greater situational awareness due to improved threat detection under most battlefield environments; compatible with traditional weapon system ranges.

2. Expanded viewing capability from high-light conditions to total darkness (no light) and through battlefield obscurants. Increases capability for urban operations.

3. Improved wearing comfort due to better weight balance resulting in less fatigue.

4. Easy-to-use controls similar to proven AN/PVS-14.

5. Non-exit pupil forming eyepiece allows the soldier to maintain full field of view even as helmet shifts during vigorous physical movements.
