    High Altitude GAmma Ray (HAGAR) telescope array, which is the first stage of HImalayan Gamma Ray Observatory (HIGRO), has been successfully installed at Hanle in Himalayas and has been collecting science data since September, ...
  • A Study of Inner Solar Corona during Total Solar Eclipse of October 24, 1995 
    Saxena, A. K; Cowsik, R; Lancelot, J. P; Samson, J. P. A; Bagare, S. P; Ismail, R (Indian Institute of Astrophysics, Bangalore, 1997)
    To study the inner corona during the total solar eclipse of October 24, 1995, an experiment was setup at Kalpi, the second location of the two IIA camps. Continuous broad record at regular interval at 40ms (TV rate) using ...
  • Testing concave aspheric surfaces: use of two crossed Babinet compensators 
    Saxena, A. K; Jayarajan, A. P (Optical Society of America, 1981)
  • Theoretical fringe profiles with crossed Babinet compensators in testing concave aspheric surfaces 
    Saxena, A. K; Lancelot, J. P (Optical Society of America., 1982)
    This paper presents the theory for the use of crossed Babinet compensators in testing concave aspheric surfaces. Theoretical fringe profiles for a sphere and for an aspheric surface with primary aberration are shown. ...

    The High Altitude GAmma-Ray (HAGAR) array is a wavefront sampling array of 7 telescopes, set-up at Hanle, at 4270 m a.s.l., in the Ladakh region of the Himalayas (North India). It constitutes the first phase of the HImalayan ...
  • Wavefront sensing and evaluation using two crossed Babinet Compensators 
    Saxena, A. K; Lancelot, J. P (SPIE-The International Society for Optical Engineering, 1990)
    The use of crossed Babinet Compensator (B. C.) combination as simple and effective device for wavefront sensing and evaluation has been described. This method can be utilized for on line evaluation of the wavefront or the ...
