Research Topics


To support the Army Research Laboratory's development of high power, continuous wave laser illuminator for a unique surveillance ladder, Physical Optics corporation proposes a nonimaging beam combiner-collimator for imaging ladder applications. The proposed NIBCC will produce an extremely high quality collimated beam with 0.5 mrad divergence. It will be rugged and stable over harsh battlefield conditions, as well as inexpensive to produce. The proposed NIBCC will be 10 times more compact than conventional optical design technology, such as optical telescopes or collimators. The key feature of the proposed NIBCC is a special arrangement of imput light delivery fiber with focusing gradient index lens assemblies. All the proposed elements can be mass produced, so the NIBCC can be manufactured at low costs and with reliable replication methods.BENEFITS: The proposed high efficiency beam combiner can be used in many military and civilian applications. Civilian uses include ladars and illumination systems for atmospheric measurements, collision avoidance systems, and terrain mapping.
