dc.description.abstract |
A state of art near IR polarimeter was designed and developed at Physical Research Laboratory, Ahmedabad and the polarimeter is operational for the last three years. During the last one year a new mode of operation has been implemented to measure polarization of extended sources. The modulation of incoming light signal is generated by fast rotating half wave plate (10 revolution/sec which generates 40 Hz modulation of polarized light). The fast modulation takes care of sky background variation. The technical details are discussed in this paper. |
