Abstract

This paper presents new physical concept and Hardware-in-the-Loop Facility for simulating cold background and/or target in 3-5 μm and 8-12 μm atmospheric transparency windows. The goal for this work is the demonstration of scene projector capable of static and dynamic (>20 kHz frame rate) simulating both point and extended targets across low apparent temperature background (≥210 K in 8-12 μm band) even if a device itself is kept at T≥300 K. We show that these record parameters as well as a possibility to dynamically erase a target (low observable simulation) are easy to achieve by manipulating the below-bandgap local emissivity of initially transparent scene made of Ge or Si and exposed in front of cold screen.
