High resolution imaging by employing passive and active approaches
Swapan K. Saha
This article begins with the discussions on the formation of speckles in the case of non-coherent quasi monochromatic source and of ways to detect them. Prior to this, a brief intr…
Speckle interferometric observations of close binary stars
S. K. Saha, V. Chinnappan, L. Yeswanth +1
Speckle interferometric technique is employed to record a series of hundreds of short-exposure images of several close binary stars with sub-arcsecond separation through a narrow b…
Performance of the low light level CCD camera for speckle imaging
S. K. Saha, V. Chinnappan
A new generation CCD detector called low light level CCD (L3CCD) that performs like an intensified CCD without incorporating a micro channel plate (MCP) for light amplification was…
Auto-correlation of Binary stars
S. K. Saha, D. Maitra
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 centr…
Perspective of long baseline interferometry
S K Saha, S. Morel
This article is a sort of sequel of the earlier extensive review by Saha (1999a) where emphasis was laid down on the ground based single aperture, as well as on the working long ba…
Speckle Imaging: a boon for astronomical observations
S K Saha
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…
