The coherent differential imaging on speckle area nulling (CDI-SAN) method for high-contrast imaging under speckle variation
Jun Nishikawa
Differential imaging is a postprocessing method to obtain high contrast, often used for exoplanet searches. The coherent differential imaging on speckle area nulling (CDI-SAN) meth…
Coronagraph Experiment on Dark-hole Control by Speckle Area Nulling Method
Masahito Oya, Jun Nishikawa, Masaaki Horie +7
In high-contrast imaging optical systems for direct observation of planets outside our solar system, adaptive optics with an accuracy of lambda/10,000 root mean square is required…
Stellar Imaging Coronagraph and Exoplanet Coronal Spectrometer: Two Additional Instruments for Exoplanet Exploration Onboard The WSO-UV 1.7 Meter Orbital Telescope
Alexander Tavrov, Shingo Kameda, Andrey Yudaev +11
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 operat…
Fiber mode scrambler for the Subaru infrared Doppler instrument (IRD)
Masato Ishizuka, Takayuki Kotani, Jun Nishikawa +4
We report the results of fiber mode scrambler experiments for the Infra-Red Doppler instrument (IRD) on the Subaru 8.2-m telescope. IRD is a fiber-fed, high precision radial veloci…
The Subaru Coronagraphic Extreme Adaptive Optics system: enabling high-contrast imaging on solar-system scales
N. Jovanovic, F. Martinache, O. Guyon +35
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is a multipurpose high-contrast imaging platform designed for the discovery and detailed characterization of ex…
