Paper Abstract

Laboratory investigations and development of space-based ultraviolet sensors have been done in Russia for over 20 years now. We have developed and continue to perfect the UV sensitive photocathodes, photosensitive transducers with luminescent screen for visualization of the UV image. Development of highly sensitive time-coordinate photoreceiving sensors is under way now including those on the basis of microchannel plates (MCP) operating in the photoelectrocounting mode, where photocathodes are employed. A peculiarity of this development is the fusion of photoreceiving unit with high performance computers, a new technology for registration of the enhanced photo current and new methods for computation and identification of the moving low contrast objects. Integral photoreceiving units with the very narrow selectivity by frequency have been developed on the basis of matrix chambers and photometers. For operation in the UV band CCD arrays are also used but their sensitivity is lower than that of the microchannel plates. It is possible to compensate the disadvantages of the CCD and the MCP devices by employment of photoelectron structures with memory, which are now at the stage of theoretic validation and laboratory research. Results achieved in development of key elements for new UV sensors and the experience of space studies by means of orbital sensors enable us to move to a new concept involving the use of small size spacecraft for the ecological monitoring of the earth and the near Earth space including their employment for surveillance of the small-size space debris.
