Princeton Infrared Technologies, Inc. (PIRT), specialists in indium gallium arsenide (InGaAs) imaging technology and affordable shortwave-infrared (SWIR) linescan cameras, visible-SWIR science cameras, and 1- and 2-D imaging arrays, announces a Phase II Small Business Innovation Research (SBIR) award from the Missile Defense Agency (MDA) to fund the development of a 128x128 on 50µm pixel pitch radiation hardened Laser Detection and 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 ROIC and operated with camera electronics.
In Phase I, PIRT developed the InGaAsP APD material structure and a unique ROIC circuit optimized for the application.
Martin H. Ettenberg, Ph.D., president of Princeton Infrared Technologies, Inc., notes, “We are excited about this Phase II research. The new APD detector structure combined with this unique ROIC design will enable an exciting space-based 3D LADAR system.”
