Control of the Optical Wavefront in Phase and Amplitude by a Single LC-SLM in a Stellar Coronagraph Aiming for Direct Exoplanet Imaging

Autor: Andrey Yudaev, Alla Venkstern, Irina Shulgina, Alexander Kiselev, Alexander Tavrov, Oleg Korablev

Publikováno v: Photonics, Vol 11, Iss 4, p 300 (2024)

This article presents a novel approach to actively compensate wavefront errors in both phase and amplitude using a Liquid Crystal Spatial Light Modulator (LC-SLM) for direct exoplanet imaging. This method involves controlling the wavefront to address

Wavefront Sensing by a Common-Path Interferometer for Wavefront Correction in Phase and Amplitude by a Liquid Crystal Spatial Light Modulator Aiming the Exoplanet Direct Imaging

Autor: Andrey Yudaev, Alexander Kiselev, Inna Shashkova, Alexander Tavrov, Alexander Lipatov, Oleg Korablev

Publikováno v: Photonics, Vol 10, Iss 3, p 320 (2023)

We implemented the common-path achromatic interfero-coronagraph both for the wavefront sensing and the on-axis image component suppression, aiming for the stellar coronagraphy. A common-path achromatic interfero-coronagraph has its optical scheme bas

Testing of a Stellar Interference Coronagraph as Part of a Ground-Based Telescope

Autor: V. V. Barke, A. V. Tavrov, A. A. Venkstern, A. V. Kiselev, Inna Shashkova, Andrey Yudaev, O. Ya. Yakovlev

Publikováno v: Solar System Research. 55:367-378

Direct exoplanet imaging with a stellar coronagraph increases the contrast of the image in the diffraction vicinity of the star. Insufficient reduction of the stellar background is due to the required quality of the wavefront, which exceeds the capab

International audience; Most transit exoplanets (85%) were discovered with the Kepler space telescope. However, the mass, which was measured mainly with the radial velocity method, is known only for ~15% of them. The mass of an exoplanet may be estim

Stellar imaging coronagraph and exoplanet coronal spectrometer: two additional instruments for exoplanet exploration onboard the WSO-UV 1.7-m orbital telescope

The World Space Observatory for Ultraviolet (WSO-UV) is an orbital optical telescope with a 1.7-m diameter primary mirror currently under development. The WSO-UV is aimed to operate in the 115- to 310-nm UV spectral range. Its two major science instr
