- W1982023304 abstract "The 2.5m optical/infrared telescope is an F/8 telescope comprising one Cassegrain foci, two Nasmyth foci and two student Nasmyth foci. This paper presents a brief description of the physical structure, conceptual design, hardware implementing measure and software structure in the positioning control system of M<sub>2</sub>&M<sub>3</sub>. The graphical user interface application (Qt) is adopted to design the software. During the full working range the M<sub>2</sub> focus and decenter achieve the positioning repeatability is better than ±4μm and the M<sub>2</sub> tilt is better than 10 μrad. The M<sub>3</sub> angular positioning and locking accuracy is better than 10 arcsec and repeatability is better than 2 arcsec RMS." @default.
