The effectiveness of a high energy laser weapon in a given engagement can be enhanced via environmental situational awareness. This technology is a light detection and ranging sensor that measures atmospheric extinction as a function of range and direction around a vessel. The sensor is highly compact, ruggedized, and automated. Initial targeted platforms include high energy laser weapon system demonstrators. The system design has undergone extensive thermo-elastic modeling to ensure that alignment will be maintained in operation. The system is being prototyped and its functionality verified. Physical Sciences Inc. specializes in providing advanced electro-optic-based active and passive sensors for critical problems in remote sensing. Our goal is to integrate and transition this technology into government and prime contractor systems requiring environmental situational awareness.
