Beam Irradiance on Target System (BITS)

The Beam Irradiance on Target System (BITS) is a high energy laser (HEL) sensor array that directly measures the beam irradiance profile of HEL weapons. The BITS is a sensor array composed of 105 sensors arranged in a hexagonal pattern over a circular area and it is designed to withstand direct exposure to continuous wave (CW) lasers at threat irradiance levels. The sensor array spatially and temporally samples HEL beam profiles and is the only reusable and direct (on target) measurement system of its type. The BITS represents the state-of-the-art in directed energy test and evaluation HEL sensors.
