Electronically Scanned LADAR

ABSTRACT: To address the Air Force"s need for non-mechanically steered 3D imaging LADAR, Physical Optics Corporation (POC) proposes to develop a new Electronically Scanned LADAR (ESLADAR), based on a novel integrated nonmechanical high-speed ferroelectric liquid-crystal (FLC) spatial light modulator (SLM) as a phased-array based scanner with 3D flash mosaic imaging. POC"s ESLADAR offers high precision for improved 3D imaging area rates and fast scan laser beams over a large FOV to 5°, directly addressing the acquisitions platform requirements of the Air Force. Innovation in design allows placement of the ESLADAR in front or behind midwave infrared forward-looking infrared optics. In Phase I, POC plans to design, develop, and evaluate the ESLADAR concept, using a computer model. We will build a proof-of-concept prototype, showing the non-mechanical beam steering concept, using the FLC SLM to achieve the required steering rate and resolution. Based on this prototype, in Phase II, POC will develop and implement a breadboard sensor demonstrating mosaic imaging over a 5 deg x 5 deg FOV, with steering rates and resolutions defined in Phase I. In Phase II, the ESLADAR will fit the SWaP constraints of a tactical pod. BENEFIT: Commercial applications will include airborne, ground-based, and subsurface 3D LADAR imaging systems; detection of littoral zone targets; natural disaster assessments; coastal zone surveys; environmental assessments; and search-and-rescue systems. POC"s ESLADAR can also provide remote surveillance at U.S. borders, 3D mapping, mission planning, 3D simulation, obstacle identification, and autonomous navigation under rugged conditions. The technology is perfect for aerial drones, terrestrial drones, and robots because it is designed for UAVs with small size, light weight, and low power consumption. It also has medical, manufacturing, and scientific applications.
