Abstract

This paper presents a new infrared imaging system, SIRIS (Short InfraRed Imaging System) that was entirely developed in LPENS of ENS Paris. It is designed around a hybrid CMOS InGaAs FPA from NIT (New Imaging Technologies). This detector was originally intended for industrial high dynamic applications, however through innovative controls and new readout methods, it became fully exploitable for low noise scientific applications. The SIRIS camera is aimed at cutting-edge applications, like astronomy ones, that can take advantage of all of its improved characteristics to gain in signal to noise ratio, dynamic, resolution and optimization of acquisition times. We took advantage of the availability of the 1 m telescope at the Pic du Midi Observatory to test the camera and develop it for astronomical applications with demanding requirements in terms of both detection and dynamic range. This system, with its specific SWIR sensor, will be presented, illustrated through its recent observational results.
