  • Characterization of a photon counting detector and Development of an attitude sensor for high altitude balloon experiments 
    Mathew, Joice (Indian Institute of Astrophysics, 2013-08)
    The information contained in an optical image can be expressed as the spatial and temporal variation in number of photons at very low light level. The high gain Micro Channel Plate (MCP) image intensifier that constitutes ...
  • Low-cost Raspberry Pi star sensor for small satellites 
    Bharat Chandra, P; Sarpotdar, Mayuresh; Binukumar, G; Rai, Richa; Mohan, Rekhesh; Mathew, Joice; Safonova, M; Murthy, J (SPIE-Society of Photo-Optical Instrumentation Engineers, 2022-07)
    We present a low-cost Raspberry Pi-based star sensor StarberrySense using commercial-off-the-shelf components, developed and built for applications in small satellites and CubeSat-based missions. A star sensor is one of ...
  • Measurements of Gondola Motion on a Stratospheric Balloon Flight 
    Safonova, M; Nirmal, K; Sreejith, A.G.; Satpodar, Mayuresh; Suresh, Ambily; Prakash, A; Mathew, Joice; Murthy, J; Anand, D; Karpardhi, B.V.N.; Suneel Kumar, B; Kulkarni, P.M. (Indian Institute of Astrophysics, 2016)
    Balloon experiments are an economically feasible method of conducting observations in astron- omy that are not possible from the ground. The astronomical payload may include a telescope, a detector, and a pointing/stabilization ...
  • The near ultraviolet transient surveyor (NUTS): An ultraviolet telescope to observe variable sources 
    Ambily, S; Sarpotda, Mayuresh; Mathew, Joice; Binukumar, G; Sreejith, A. G; Nirmal, K; Murthy, J; Safonova, M; Mohan, Rekhesh; Aggarval, Vinod Kumar; Nagabhushanam, S; Jeeragal, Sachin (Springer, 2022-08)
    Observing the ultraviolet (UV) sky for time-varyiable phenomena is one of the many exciting science goals that can be achieved by a relatively small aperture telescope in space. The Near Ultraviolet Transient Surveyor ...
  • Ultra violet space instrumentation and studies of astronomical objects 
    Mathew, Joice (Indian Institute of Astrophysics, 2018-06)
    The Ultraviolet (UV) domain plays an important role in studying transient events, the atmosphere of stars and planets, characteristics of the interstellar medium, young stellar populations, physical properties of galaxies ...
