Angle measurement method of electronic speckle interferometry based on Michelson interferometer

Autor: Siyuan, Zhu, Tao, Li, Zhongshan, Chen, Xin, Li

{This paper proposes an angle measurement method based on Electronic Speckle Pattern Interferometry (ESPI) using a Michelson interferometer. By leveraging different principles within the same device, this method achieves complementary advantages acro

Precision speckle interferometry with CMOS detector

Autor: Strakhov, I. A., Safonov, B. S., Cheryasov, D. V.

Speckle polarimeter (SPP) is a facility instrument of the 2.5-m telescope of the Caucasian Mountain Observatory of SAI MSU. By design it is a combination of a speckle interferometer and a dual--beam polarimeter. In 2022 we performed a major upgrade o

Orbits of Binary Stars: from Visual Measures to Speckle Interferometry

Autor: Tokovinin, Andrei

Knowledge of the orbits of visual binary stars has always been one of the fundamentals of astronomy. Based historically on the visual measures, nowadays the orbits rely more (or exclusively) on the accurate speckle data. This prompts reconsideration

Speckle Interferometry at SOAR in 2023

Autor: Tokovinin, Andrei, Mason, Brian D., Mendez, Rene A., Costa, Edgardo

Results of the speckle-interferometry observations at the 4.1 m Southern Astrophysical Research Telescope (SOAR) obtained during 2023 are presented: 1913 measurements of 1533 resolved pairs or subsystems (median separation 0.16") and non-resolutions
