  • Design, development, and validation of a segment support actuator for the prototype segmented mirror telescope 
    Deshmukh, P. G; Mandal, A; Parihar, P. S; Nayak, D; Mishra, Deepta Sundar (SPIE-The International Society for Optical Engineering, 2018-01)
    Segmented mirror telescopes (SMT) are built using several small hexagonal mirrors positioned and aligned by the three actuators and six edge sensors per segment to maintain the shape of the primary mirror. The actuators ...
  • Dynamic Loading Assembly for Testing Actuators of Segmented Mirror Telescope 
    Prasanna Deshmukh; Parihar, P. S; Balasubramaniam, K. A; Mishra, Deepta Sundar; Mahesh, P. K (World Scientific Publishing Co., 2017-09)
    Upcoming large telescopes are based on Segmented Mirror Telescope (SMT) technology which uses small hexagonal mirror segments placed side by side to form the large monolithic surface. The segments alignment needs to be ...
  • Primary Mirror Active Control System Simulation of Prototype Segmented Mirror Telescope 
    Prasanna Deshmukh; Mishra, Deepta Sundar; Parihar, P. S; Vedashree (IEEE, 2017-01)
    The upcoming large astronomical telescopes are trending towards the Segmented Mirror Telescope (SMT) technology, initially developed at the W M Keck Observatory in Hawaii, where two largest SMTs in the world are in use. ...
  • A soft actuator for prototype segmented mirror telescope 
    Prasanna, Deshmukh; Parihar, P. S; Mishra, Deepta Sundar; Prakash, Ajin; Kemkar, P. M. M (SPIE-The International Society for Optical Engineering, 2016-07)
    The Segmented Mirror Telescopes (SMT) are built using small hexagonal mirror segments placed side by side to form a monolithic primary mirror of very large size. The effective figure of such a segmented primary mirror is ...
