论文摘要

我们介绍了用于可见波长中恒星的高角度分辨率观测的I2C恒星强度干涉仪的当前状态。在这些程序中,我们介绍了该乐器的最新技术改进,并使用小直径光学望远镜阵列进行了持续的运动结果。将倾斜的自适应光学单元集成到光学系统中,以将光注射稳定到光纤中。该设置已在Abservatoire delaCôted'Azur的Calern高原遗址上成功测试了几个设施。其中包括C2PU天文台的1 M直径望远镜之一,可移植的1 m直径望远镜以及1.5 MMéo望远镜。为了更好地限制天上测量,使用高分辨率光谱仪在实验室中表征了仪器的光谱传递。还用VLTI的两个辅助望远镜测试了该系统,从而成功进行了三颗恒星的时间和空间相关测量。

We present the current status of the I2C stellar intensity interferometer used towards high angular resolution observations of stars in visible wavelengths. In these proceedings, we present recent technical improvements to the instrument, and share results from ongoing campaigns using arrays of small diameter optical telescopes. A tip-tilt adaptive optics unit was integrated into the optical system to stabilize light injection into an optical fiber. The setup was successfully tested with several facilities on the Calern Plateau site of the Observatoire de la Côte d'Azur. These include one of the 1 m diameter telescopes of the C2PU observatory, a portable 1 m diameter telescope, and also the 1.5 m MéO telescope. To better constrain on-sky measurements, the spectral transmission of instrument was characterized in the laboratory using a high resolution spectrograph. The system was also tested with two of the auxiliary telescopes of the VLTI resulting in successful temporal and spatial correlation measurements of three stars.
