This paper presents the latest developments in instrumentation for military laser range-finder/designator (LRF/D) test and evaluation. SBIR has completed development of two new laser test modules designed to support a wide range of laser measurements including range accuracy and receiver sensitivity, pulse energy and temporal characteristics, beam spatial/angular characteristics, and VIS/IR to laser co-boresighting. The new Laser Energy Module (LEM) provides automated, variable attenuation of UUT laser energy, and performs measurement of beam amplitude and temporal characteristics. The new Laser/Boresight Module (LBM) supports range simulation and receiver sensitivity measurement, performs UUT laser beam analysis (divergence, satellite beams, etc), and supports high-accuracy co-boresighting of VIS, IR, and laser UUT subsystems. The LBM includes a three-color, fiber-coupled laser source (1064, 1540, and 1570 nm), a sophisticated fiber-optic module (FOM) for output energy amplitude modulation, a 1-2 μm SWIR camera, and a variety of advanced triggering and range simulation functions.
