During 1991.12 to 1993.12 he joined the VLTI group in ESO to do the beam combiner telescope design work. 

　　He has got some awards like the  State science and technology progress prize for 1.56m astrometry telescope 、 the HL HL Prize etc. and has been accepted as a member of Chinese Academy of Engineering in 1995. 

　　The major telescopes he designed are; 

　　1. The dual-rate lunar position camera (1965). 

　　2. A photographic zenith tube(1976). 

　　3.  20cm Maksutov  and a Schmidt  telescope for solar eclipse (1980). 

　　4. 1.56m astrometry telescope (1990) 

　　5. 1m laser ranging telescope (2009) 

　　6. 1m laser communication telescope (2011)
