LISS（线成像仪和狭缝摄谱仪）是配备液晶标准具和低分辨率棱镜的成像仪和摄谱仪。它专门用于观察和绘制天文物体的发射线和吸收线。全耗尽背照式 2K x 1K Hamamatsu CCD 在光学波段的较红波长处具有高灵敏度，使该仪器能够在 [SIII]λλ 906.9/953.2 nm 等发射线的成像和光谱观察中提供良好的性能。我们于2012年9月/10月和2013年6月/7月在北海道大学的1.6米皮尔卡望远镜成功进行了调试观测。在本文中，我们描述了LISS的设计和性能以及其早期观测结果和未来展望。
LISS (Line Imager and Slit Spectrograph) is an imager and spectrograph equipped with a liquid crystal etalon and a low resolution grism. It is specialized to observe and map the emission and absorption lines of astronomical objects. A fully depleted and back illuminated 2K x 1K Hamamatsu CCD which has high sensitivity at redder wavelengths in optical bands enables this instrument to give a good performance in imaging and spectroscopic observations of emission lines such as [SIII]λλ 906.9/953.2 nm. We successfully carried out commissioning observations at the 1.6-m Pirka telescope of Hokkaido University in September/October 2012 and June/July 2013. In this paper, we describe the design and performance of LISS as well as its early observational results and future prospects.
