In 2017Associate Prof. Shihai Yang and Prof. Guomin Wang of Nanjing Institute of Astronomical Optics & Technology NIAOT won an invention paten authorized in the United States of Americawhich is named Control System for implementing Non-linear interference / Compensation for Torsion Angle of Astronomical TelescopeDetails are as follows

Control System for implementing Non-linear interference/Compensation for Torsion Angle of Astronomical TelescopePatent No. 9,599,809 B2Issue date: 03/21/2017Application No. US14/423,735 (based on PCT/CN2013/077907)

It’s the first foreign authorized invention paten of NIAOT

A control system for implementing non-linear interference compensation for a torsion angle of an astronomical telescope is providedBy the torsion angle compensation and amendment in real timedriving wheel rotation axial line and driven wheel rotation axial line are kept parallel to each other in order to form compensation to torsion angleBy this wayfluctuation of the system is removed and telescope can track in higher accuracy and move stably in ultra-low speed
