Description
The VERITAS Imaging Air Cherenkov Telescope array IACT) was augmented in 2019 with high-speed focal plane electronics to allow the use of VERITAS for Stellar Intensity Interferometry (SII) observations. Since that time, a number of improvements have been made to increase the sensitivity of VSII and increase the speed of nightly data processing. This poster will describe the use of IACT arrays for performing ultra-high resolution (sub-milliarcsecond) astronomical observations. The poster presentation will include a description of the VERITAS-SII focal plane, data acquisition, and data analysis systems. The poster concludes with an evaluation of the VSII observatory’s system’s current sensitivity, and plans for a future upgrade of the VSII instrument.
