PRINCETON INFRARED TECHNOLOGIES INC — Department of Defense STTR Phase I: AF20C-TCSO1

Description

Princeton Infrared Technologies, Inc. (PIRT) will team with University of California Irvine (UCI) to develop a room temperature imager with detectivity from 3 to 12 ?m spanning mid-wave infrared (MWIR) and longwave infrared (LWIR) spectral range using non-degenerate two-photon absorption.  This novel detection strategy captures MWIR/LWIR images at high pixel densities, high sensitivity, and low noise without cooling.  Currently, MWIR and LWIR imaging requires expensive low-bandgap semi-conducting materials, such as HgCdTe.  Cooled cameras that are commonly used to cover the entire 3 to 12 ?m spectrum have low pixel densities such as 128x128, precluding the use of high definition (HD) sampling for acquiring high quality videos in use for applications such as microscopy and hyperspectral imaging.  In this program, the team will deliver a 1280x1024 resolution camera using a custom InxGa1 xAsyP1-y array integrated with optics and high speed lasers that operate at room temperature to image light from 3 to 12 ?m at video rates.
