dc.description.abstract	India is planning to build a large Optical/Infrared Telescope of 4 to 5 M in size. This telescope will adopt most of the features of the New Technology Telescope including active and adoptive optics corrections for achieving improved image quality. Keeping this in view a prototype active optics system for a 27 inch thin mirror is being developed at Indian Institute of Astrophysics. A new digital polarization shearing interferometer will be used for wavefront sensing. The paper describes in detail the procedure for wavefront sensing and the approach for the active correction.	en
