Imaging Science

Research area:

  • Basic and applied research directed to manufacturing light- and radiation-sensitive materials (silver and nonsilver systems), for image recording.
  • Research into novel applications of photochemical and photophysical processes.
  • Automation and computerization of sensitometric, structurometric and colorimetric measurements.
  • Computer-aided modeling of the radiation-sensitive layer properties.
