The Safran Defense & Space, Inc. (Formerly-Optics 1) Thermal Augmentation Device (TAD) is based on the AN/PAS-29B Enhanced Clip-On Thermal Imager (ECOTI), and is a small, lightweight system that clips on to almost any existing Night Vision Goggle system. TAD creates an instant thermal fusion capability without any permanent modification to the device or system by projecting a thermal overlay into the intensified image, providing the user with superior detection, situational awareness and identification capabilities compared to using an I2 or thermal system by itself.
I2 / Thermal Fusion is becoming THE standard for headborne Visual Augmentation Systems, with devices like the ENVG-B and SBNVG becoming standardized across close combat formations across the DoD. I2 / Thermal Fusion offers a significant edge to users in extreme low light conditions and heavily wooded or shaded areas, including subterranean operations, as we begin to face adversaries with their own night vision capabilities.
