Abstract

The authors are constructing an infrared imager to evaluate and monitor the performance of the Japanese National Large Telescope "Subaro" during the commissioning phase. The system consists of two array cameras, one for near-infrared and one for mid-infrared, and captures simultaneous images at both wavelengths fast enough to freeze the seeing. The data will be used to study image reconstruction techniques suited for mid-infrared. The system also has a telescope emissivity mapper that images the telescope pupil and its surroundings onto a third array. The first phase the system consists of a two-wavelength imager using a single 256×256 InSb array and an emissivity mapper using a 128×128 InSb array. This paper describes the background and the design concept of the system.
