PIRT announces Phase II Award from MDA to develop ToF camera for 3D imaging
Princeton Infrared Technologies Inc (PIRT) of Monmouth Junction, NJ, USA – which specializes in shortwave-infrared (SWIR) linescan cameras, visible-SWIR science cameras, and 1D and 2D imaging arrays based on indium gallium arsenide (InGaAs) – has announced a Phase II Small Business Innovation Research (SBIR) award from the US Missile Defense Agency (MDA) to fund the development of a 128x128 50µm-pixel-pitch radiation-hardened laser detection & ranging (LADAR) system.
Princeton Infrared Technologies will focus on developing a flash LADAR module featuring indium gallium arsenide phosphide (InGaAsP) linear-mode avalanche photodiodes (APDs) optimized for detection of 1.06µm light hybridized to a custom readout integrated circuit (ROIC) and operated with time-of-flight (ToF) camera electronics.
In Phase I, PIRT developed the InGaAsP APD material structure and a unique ROIC circuit optimized for the application.
“The new APD detector structure, combined with this unique ROIC design, will enable an exciting space-based 3D LADAR system,” says PIRT’s president Martin H. Ettenberg Ph.D.
Princeton Infrared Technologies awarded AFRL SBIR Phase II contract for coherent LADAR detectors
