2019年，VERITAS成像空中切伦科夫望远镜阵列（IACT）得到了高速焦平面电子设备的增强，允许使用VERITAS进行恒星强度干涉测量（SII）观测。从那时起，已经实施了几项改进，以提高VERITAS恒星强度干涉仪（VSII）的灵敏度，并提高夜间数据处理的速度。这张海报将描述IACT阵列在短可见波长下进行超高分辨率（亚毫弧秒）天文观测的用途。海报展示将包括对VERITAS-SII焦平面、数据采集和数据分析系统的描述。海报最后描述了VSII仪器未来升级的计划。
The VERITAS Imaging Air Cherenkov Telescope array (IACT) was augmented in 2019 with highspeed focal plane electronics to allow the use of VERITAS for Stellar Intensity Interferometry (SII) observations. Since that time, several improvements have been implemented to increase the sensitivity of the VERITAS Stellar Intensity Interferometer (VSII) and increase the speed of nightly data processing. This poster will describe the use of IACT arrays for performing ultrahigh resolution (sub-milliarcsecond) astronomical observations at short visible wavelengths. The poster presentation will include a description of the VERITAS-SII focal plane, data acquisition, and data analysis systems. The poster concludes with a description of plans for future upgrades of the VSII instrument.
