摘要

TIFR近红外成像相机ii (TIRCAM2)正在印度北阿坎德邦纳尼塔尔的Aryabhatta观测科学研究所(ARIES)运营的Devasthal光学望远镜(DOT)上使用。除了正常的全画幅观测外，还需要高速子阵观测，用于月球掩星和星斑观测。通过在计算机和控制器DSP代码级对相机软件进行适当的修改，在TIRCAM2中实现了快速子阵列模式。采用快速子阵列观测模式进行了成功的观测。

TIRCAM2 fast sub-array readout mode for lunar occultation studies

TIFR Near Infrared Imaging Camera-II (TIRCAM2) is being used at the Devasthal Optical Telescope (DOT) operated by Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, Uttarakhand, India. In addition to the normal full frame observations, there has been a requirement for high speed sub-array observations for applications, such as lunar occultation and star speckle observations. Fast sub-array modes have been implemented in TIRCAM2 with suitable changes in the camera software at the computer and controller DSP code level. Successful observations have been carried out with the fast sub-array mode of observation.
