The AN/PSQ-36 Fusion Goggle System (FGS) is a goggle that combines both standard I2 night vision with thermal imaging in one fused system.
The FGS allows the operator to adjust the viewed image from 100% I2 to 100% thermal, or a varying mix of the two. The system amplifies available light and thermal signatures and fuses them together to produce a clear image under adverse conditions. The FGS provides unparalleled image resolution in situations where active infrared (IR) illumination is not an option.
