The prospects of modern CMOS and CCD detectors for wide field telescopes
Abstract
The paper presents the latest developments and trends in large-format CMOS and CCD detectors of the optical range, and considers the possibility of their use in the INASAN telescopes. Improvement of classical CCD goes in the direction of increasing parallelism (CCD250-82), extending the spectral range to the IR region, build 4-side buttable devices. Scientific 3-side buttable CMOS and CMOS mosaic based on it (TAOS-II) demonstrates the potential of using CMOS with large telescopes. Mass production of relatively inexpensive scientific CMOS (GSENSE6060) of the 6 × 6 k (60 × 60 mm) format and in the future 9 × 9 k (90 × 90 mm) allow to improve the efficiency of survey telescopes with apertures up to 1 m. CMOS with a very small pixel (3-5 μm) of more than 100 Mpixel format allow increasing the information capacity of wide field telescopes of moderate apertures. The experimental curved CMOS (CMV20000) will allow implementing ultra-wide field telescopes of small apertures and curved mosaic detectors for large telescopes in the future.
