摘要:

红外照相机是AKARI卫星上的两个仪器之一。除了AKARI的定点观测模式从1.8-26.5um深度成像外,它还具有光谱范围内的光谱能力。通过用滤光轮上的透射型色散器代替成像滤光器,它提供了具有狭缝或宽成像视场(约10'X10')的低分辨率(lambda/d_lambda ~ 20-120)光谱学。IRC光谱模式在空间红外飞行任务中是独一无二的,因为它能够在近红外和中红外波长范围内进行灵敏的宽场光谱勘测。本文介绍了红外光谱仪的技术指标及其在轨性能。

英文摘要:

The Infrared Camera (IRC) is one of the two instruments on board the AKARI satellite. In addition to deep imaging from 1.8-26.5um for the pointed observation mode of the AKARI, it has a spectroscopic capability in its spectral range. By replacing the imaging filters by transmission-type dispersers on the filter wheels, it provides low-resolution (lambda/d_lambda ~ 20-120) spectroscopy with slits or in a wide imaging field-of-view (approximately 10'X10'). The IRC spectroscopic mode is unique in space infrared missions in that it has the capability to perform sensitive wide-field spectroscopic surveys in the near- and mid-infrared wavelength ranges. This paper describes specifications of the IRC spectrograph and its in-orbit performance.
