论文摘要
NISP(近红外光谱仪和光度计)是两种欧几里得仪器之一。它在近红外光谱区(950-2020nm)作为光度计和光谱仪运行。该仪器由:由碳化硅结构,光学组装,滤轮机制,Grism轮机制,校准单元和热控制系统组成的冷(135 K)光学机械子系统组成仪器控制单元,通过1553公共汽车进行指挥和控制以及通过SpaceWire链接进行科学数据,该单元与航天器接口。 本文介绍了:飞行模型仪器和子系统的最终架构,以及在NISP级别和Euclid有效载荷模块在操作冷温下进行的性能和地面校准测量。
The NISP (Near Infrared Spectrometer and Photometer) is one of the two Euclid instruments. It operates in the near-IR spectral region (950-2020nm) as a photometer and spectrometer. The instrument is composed of: a cold (135 K) optomechanical subsystem consisting of a Silicon carbide structure, an optical assembly, a filter wheel mechanism, a grism wheel mechanism, a calibration unit, and a thermal control system, a detection system based on a mosaic of 16 H2RG with their front-end readout electronic, and a warm electronic system (290 K) composed of a data processing / detector control unit and of an instrument control unit that interfaces with the spacecraft via a 1553 bus for command and control and via Spacewire links for science data. This paper presents: the final architecture of the flight model instrument and subsystems, and the performance and the ground calibration measurement done at NISP level and at Euclid Payload Module level at operational cold temperature.
