Development of a high-speed image registration system based on a large-format low-noise CMOS photoreceiver
A high-speed image registration system based on a GSense4040CMT CMOS photoreceiver (GPixel, KHP) with a 4K×4K pixel format was developed and manufactured for the telescopes of SAO RAS. A new controller was developed allowing one to control the modes of operation and the thermal stabilization of the CMOS receiver, to form video data and transmit it to the control computer with a speed of up to 10 Gb/s. An effective set of programs for the class of high-speed photo receivers has been implemented. The main advantages of the developed CMOS system are the high frame readout rate (two orders of magnitude higher than the astronomical CCD systems), high sensitivity (comparable to CCD), and the large size of the receiver, which allows one to use the new image registration system for conducting quick sky surveys and obtaining images of rapidly varying astronomical objects. The developed system is expected to be used with the 6-meter BTA telescope for rapid spectroscopy.
