The Division of Science and Technology for Optical Astronomy (DSTOA) of the Shanghai Astronomical Observatory (SHAO) has been founded since 2009. As one of the primary divisions of the SHAO, the DSTOA is responsible for astronomical optical technique development. In addition to the contracture of astronomical optical telescopes and astronomical optical interferometry technique, the activities of DSTOA encompass optical and infrared instrumentation technique, design and operation of optical survey systems, digitalized photography technique, etc., and recently carried out scientific driven research on Astronomical Optical Technology. During its history of over 50 years, the DSTOA has developed various kinds of optical telescopes, such as a vacuum photographic zenith telescope (1970), a double-speed lunar camera (1970), a 1.56m astrometric telescope (1987), three 30cm photoelectric telescopes (2003), a 1m satellite laser-ranging telescope (2009), four 25cm drift-scan CCD telescopes (2010), a 1m laser communication telescope (2011), and five 30cm rotating-drift-scan CCD telescopes (2013).1.2m bifocal optical telescope（2017），bifunctional optical telescope（2018）.FocusGEO telescopes(2018) and FocusGEO II telescocpes(2020). In recent years, DSTOA has also participated in the development of two payload "multi-channel imagers" and "integral field spectrometers" on the Chinese Space Station Telescope (CSST), and is taking the lead in promoting the "earth 2.0" exoplanet detection satellite project. Presently DSTOA has 35 staff members, including one Member of the Chinese Academy of Engineering, three researcher and 15 senior engineers specializing on optics, mechanics, electronics, control software and CCD cameras.It is made up of 6 research groups as showed below. The research groups of the DSTOA include: (1) Development and Operational Maintenance of optical telescopes (PI: ZHOU Dan) (2) Astronomical optical interferometry technique (PI: CHEN Xinyang) (3) GEO Global Joint-Observation and Research Group(PI: MAO Yindun) (4) Infrared and space instrumentation technique (PI: XU Chun) (5) Digitalized photography technique (PI: ZHAO Jiianhai) (6) Exoplanet detection technique (Earth 2.0, PI: GE Jian)
