  • Auto-correlation of Binary stars 
    Saha, S. K; Maitra, D (Indian Association for the Cultivation of Science, 2001)
    Speckle interferometric technique is used to record a series of short exposure images of several close binary stars with sub-arcsecond separation through a narrow band filter centred at H$\alpha$ at the Cassegrain focus ...
  • High resolution imaging by employing passive and active approaches 
    Saha, S. K (Anita Publications, 2002)
  • Performance of the low light level CCD camera for speckle imagmg 
    Saha, S. K; Chinnappan, V (Astronomical Society of India, 2002-09)
    A new generation CCD detector caJ.led low light level OOD (L3CCD) that performs like an intensified CCD without incorporating a micro channel plate (MOP) for light amplification was procured and tested. A series of ...
  • Speckle Imaging: a boon for astronomical observations 
    Saha, S. K (Centre for Space Physics, 2003)
    The speckle imaging is a photographic technique that resolves objects viewed through severely distorted media. The results are insensitive to the errors caused by apparent size of the isoplanatic patch and the telescope ...
  • Speckle interferometric observations of close binary stars 
    Saha, S. K; Chinnappan, V; Yeshwanth, L; Anbazhagan, P (Astronomical Society of India, 2002-09)
    Speckle interferometric technique is employed to record a series of hundreds of short-exposure images of several close binary stars with sub-arc second separation through a narrow band filter at the Cassegrain focus of ...
  • Speckle interferometric observations of the collision of comet Shoemaker-Levy 9 with Jupiter 
    Saha, S. K; Rajamohan, R; Vivekananda Rao, P; Sunder, G. S; Swaminathan, R; Lokanandham, B (Astronomical Society of India, 1997)
    Speckle interferometric technique has been used to obtain a series of short exposure images of the collision of comet Shoemaker-Levy 9 with Jupiter during the period of July 17-24, 1994 using the Nasmyth focus of 1.2 meter ...
  • Techniques for Achieving Higher Spatial Resolution 
    Sridharan, R (Astronomical Society of India, 2002-09)
    The application of speckle and interferometric techniques for imagmg small scale solar features is studIed In detail. A computer program(speckle code) was dt!v(-joped to analyze the speckle data. The capability of the ...
