About

This community houses the papers, scholarship and creative works produced by the CSUN Department of Physics and Astronomy's faculty and students. Faculty are given individual collections to showcase their work. Student works, including papers and other assignments, are kept within individual course collections (i.e. BIOL 485). Master's theses for this discipline are included within this community but can also be found in the Electronic Theses and Dissertations Community.

  • Ren, Deqing; Allington-Smith, Jeremy R. (Society of Photo-Optical Instrumentation Engineers, 1999)
    A method based on the Herzberger approach has been investigated for the selection of glasses for the apochromatic correction at near-infrared (NIR) wavelength. The method avoids the algebraic complexity and simplifies the ...
  • Ren, Deqing; Wang, Haimin (Astrophysical Journal, 2006)
    We present a novel "spectral subtraction algorithm" (SSA) technique to remove speckle noise. It consists of a low-order and a high-order SSA and is based on a three-dimensional image spectroscopy in which the three-dimensional ...

    Image Rotation and Subtraction (IRS) is a high-contrast imaging technique that can be used to suppress the speckle noise and facilitate the direct detection of exoplanets. IRS is different from Angular Differential Imaging ...
  • Liu, Cheng-Chao; Ren, Deqing; Dou, Jian-Pei; Zhu, Yong-Tian; Zhang, Xi; Zhao, Gang; Wu, Zhen; Chen, Rui (Research in Astronomy and Astrophysics, 2015)
    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 4Y/D or less. Here we report our recent laboratory experiment that is close ...
  • Ren, Deqing; Dou, Jiangpei; Zhang, Xi; Zhu, Youngtian (Astrophysical Journal, 2012)
    Future ground-based direct imaging of exoplanets depends critically on high-contrast coronagraph and wave-front manipulation. A coronagraph is designed to remove most of the unaberrated starlight. Because of the wave-front ...
