A simple automated device has been developed at the Air Force Weapons Laboratory to rapidly measure integrated irradiance profiles for circular symmetric "far field" distributions. The system consists of a computer driven measurement device and interface/timing electronics. IRIS can be used with both pulsed and continuous lasers. The basic concept will be presented along with specific examples.
