The aim of this project is to develop a system for optical intensity interferometry for the H.E.S.S gamma-ray telescopes in Namibia and to perform high-angular resolution measurement of stars in the V and R bands. The proposed project consists of three modules: a) development of the light-detection and electronics chain, b) development of the mechanical and optical struture and c) development of data analysis tools. We aim to demonstrate the feasibility of the full chain developed in this proposal to measure the stellar diameters of bright stars on timescales of a few hours (detect the signal at a projected 5-m baseline within minutes).

该项目的目的是为纳米比亚的H.E.S.S伽马射线望远镜开发一个光学强度干涉测量系统，并在V和R波段对恒星进行高角度分辨率测量。拟议项目由三个模块组成：a）光检测和电子链的开发，B）机械和光学结构的开发以及c）数据分析工具的开发。我们的目标是证明在这个建议中开发的完整链的可行性，以测量明亮恒星的恒星直径的时间尺度为几个小时（检测信号在预计5米的基线在几分钟内）。
