Design and dynamics experiment of filter wheel mechanism of space coronagraph
Wei Guo, Jiangpei Dou, Mingming Xu +4
In order to realize multi-spectral imaging of space coronagraph, a compact filter wheel mechanism is designed. The filters with different spectral transmittance can be cut into the…
Performance Calibration of the Wavefront Sensor's EMCCD Detector for the Cool Planets Imaging Coronagraph Aboard CSST
Jiangpei Dou, Bingli Niu, Gang Zhao +5
The wavefront sensor (WFS), equipped with an electron-multiplying charge-coupled device (EMCCD) detector, is a critical component of the Cool Planets Imaging Coronagraph (CPI-C) on…
Portable Adaptive Optics for Exoplanet Imaging
Yongtian Zhu, Jiangpei Dou, Xi Zhang +3
The Portable Adaptive Optics (PAO) is a low-cost and compact system, designed for 4-meter class telescopes that have no Adaptive Optics (AO), because of the physical space limitati…
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…
Phase Quantization Study of Spatial Light Modulator for Extreme High contrast Imaging
Jiangpei Dou, Deqing Ren
Direct imaging of exoplanets by reflected starlight is extremely challenging due to the large luminosity ratio to the primary star. Wave-front control is a critical technique to at…
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…
