Measurement of vector magnetic fields. I - Theoretical approach to the instrumental polarisation of the Kodaikanal Solar Tower

Balasubramaniam, K. S; Venkatakrishnan, P; Bhattacharyya, J. C (D. Reidel Publishing Co., 1985-09)

The observations of Stokes line profiles require an accurate knowledge of the instrumental polarisation caused by optical components in the path of the light beam. In this context we present a theoretical approach to the ...
A personal-computer-based imaging Stokes polarimeter for solar observations

Ananth, A. V; Venkatakrishnan, P; Narayanan, R. S; Bhattacharyya, J. C (Springer, 1994-05)

For measurements of vector magnetic field over solar active regions, a Stokes polarimeter for studying the polarization profiles on selected spectral lines is described. This paper gives details of the relevant charged ...
