    Liger is a next-generation near-infrared (0.81 - 2.45 µm) integral field spectrograph (IFS) and imaging camera for the W. M. Keck Observatory (WMKO) adaptive optics (AO) system. The instrument concept originated by ...
  • Simulation and experimental study of the OTF based alignment and phasing of segmented mirrors 
    Radhika, Dharmadhikari; Parihar, P. S (SPIE - Society of Photo-Optical Instrumentation Engineers, 2024-06)
    For a segmented mirror telescope, the desired resolution can only be achieved when all the segments are precisely co-aligned, co-focused and co-phased. The process of minimization of the piston errors is called co-phasing, ...
