Dual Mode Eye-Safe LIDAR/Active Imaging Sensor

Physical Sciences Inc. (PSI) has been awarded a research contract from the U.S. Army to design, develop, and demonstrate a Dual Mode, Eye-Safe LIght Detection and Ranging (LIDAR)/Active Imaging Sensor.

This sensor will address the need for multifunctional capability in situational awareness for future forces detailed to reconnaissance and force protection in domains including chemical and biological hazards. The Dual Mode Active Sensor will have two modes of operation, an elastic backscatter LIDAR for detection and tracking of chemical and biological warfare agent aerosol plumes, as well as an active Short Wave InfraRed (SWIR) imager for perimeter surveillance where both modes employ the same laser transmitter operating at an eye-safe wavelength of 1.5μm. The sensor size and power requirements will be compatible with deployment on currently operational vehicles such as the Nuclear, Biological, and Chemical Reconnaissance Vehicle.

The Dual Mode, Eye-Safe LIDAR/Active Imaging Sensor will provide wide area persistent surveillance of aerosolized biological and chemical warfare agents as well as situational awareness in cases of low visibility and nighttime operation. Its benefits include aerosol monitoring at the eyesafe wavelength and the ability to perform covert nighttime active imaging. This capability is well suited to forward operating base protection, and a smaller version could be used for standoff sensing in urban settings and large outdoor venues such as sporting events or concerts.
