Dynamic Visible-To-Infrared Converter
Abstract
This report results from a contract tasking Institute of Semiconductor Physics, Ukrainian Academy of Sciences as follows: Semiconductor based pixel-less Dynamic Infrared Scene Projector (DISP) successful in generating of high-speed (microseconds range) broad band (3-16 microns) IR scenery is to be developed both theoretically and experimentally. For this purpose non-equilibrium thermal emission of semiconductors in the spectral range beyond the fundamental absorption region provoked by the band-to-band photogeneration of excess carriers (visible pumping) will be utilized for the first time (visible-to-infrared conversion). Such performance capabilities as maximum simulated temperature, noise equivalent temperature difference, dynamic range, spatial resolution of converted images and rise-fall time will be estimated and measured. The device prototype made of Ge will be tested in the Ukraine and USA. By the end of the work a Ukrainian patent will be requested, scientific paper will be submitted to the international journal and results reported at the international conference.
