The backbone-residual model. Accurately characterising the instrumental profile of a fibre-fed echelle spectrograph
Zhibo Hao, Huiqi Ye, Jian Han +14
Context: Instrumental profile (IP) is the basic property of a spectrograph. Accurate IP characterisation is the prerequisite of accurate wavelength solution. It also facilitates ne…
Maunakea Spectroscopic Explorer (MSE): a preliminary design of multi-object high resolution spectrograph
Kai Zhang, Yifei Zhou, Zhen Tang +8
The Maunakea Spectroscopic Explorer (MSE) project will transform the CFHT 3.6m optical telescope to a 10m class dedicated multi-object spectroscopic facility, with an ability to me…
Design and experimental test of an optical vortex coronagraph
Chengchao Liu, Deqing Ren, Yongtian Zhu +1
The optical vortex coronagraph (OVC) is one of the promising ways for direct imaging exoplanets because of its small inner working angle and high throughput. This paper presents th…
A Transmission-Filter Coronagraph: Design and Test
Deqing Ren, Jiangpei Dou, Yongtian Zhu
We propose a transmission-filter coronagraph for direct imaging of Jupiter-like exoplanets with ground-based telescopes. The coronagraph is based on a transmission filter that cons…
Focal plane wave-front sensing algorithm for high-contrast imaging
JiangPei Dou, DeQing Ren, YongTian Zhu +1
High-contrast imaging provided by a coronagraph is critical for the direction imaging of the Earth-like planet orbiting its bright parent star. A major limitation for such direct i…
A High-contrast Imaging Algorithm: Optimized Image Rotation and Subtraction
Jiangpei Dou, Deqing Ren, Gang Zhao +3
Image Rotation and Subtraction (IRS) is a high-contrast imaging technique which can be used to suppress the speckles noise and facilitate the direct detection of exoplanets. IRS is…
A high-contrast coronagraph for earth-like exoplanet direct imaging: design and test
C. C. Liu, D. Q. Ren, J. P. Dou +5
The high-contrast coronagraph for direct imaging earth-like exoplanet at the visible needs a contrast of 10^(-10) at a small angular separation of 4 lambda/D or less. Here we repor…
An iterative wave-front sensing algorithm for high-contrast imaging systems
Jiangpei Dou, Deqing Ren, Yongtian Zhu
Wave-front sensing from focal plane multiple images is a promising technique for high-contrast imaging systems. However, the wave-front error of an optics system can be properly re…
High-contrast coronagraph for ground-based imaging of Jupiter-like planets
Jiangpei Dou, Deqing Ren, Yongtian Zhu
We propose a high-contrast coronagraph for direct imaging of young Jupiter-like planets orbiting nearby bright stars. The coronagraph employs a step-transmission filter in which th…
