CCD Controller for Astronomic Telescopes

Customer: INAF (various projects: LBT, TMG etc.)
Year: 1993 on (manufactured, with continued improvements, in 35 + sets)

The Controllers of the CTR-Ax00 series represent the result of 20 years of experience in the field of CCD/CMOS image acquisition for astronomy and spectroscopy. Main features include:

  • Correlated double sampling boards for signal conditioning, filtering and A/D conversion of (up to) 4 independent video outputs;
  • A-to-D conversion with dynamic, pixel-by-pixel correction of bias and gain, based on custom look-up tables;
  • Sequencer boards for the generation of phases and pixel processing signals necessary for the control of a wide range of scientific and industrial CCDs/CMOS;
  • low-latency output for realtime control of adaptive optics (to cater for air turbulence);
  • interface for driving CCD thermo-electric coolers (Peltier elements) and mechanisms (filter wheels, shutters, etc.
  • Ethernet Interface for Remote setup, and control and image acquisition, ideal for high-altitude installation sites;
