In astronomical observation and space object detection
larger-aperture telescopes are used widely.Liquid crystal adaptive optics imaging technology has been used in correction of the aberration caused by atmospheric turbulence.In order to verify the validity of the technology and maximize energy utilization,Zemax is used to design the liquid crystal adaptive optical system
and the characteristic of the system is evaluated.Obtained modulation transfer function(MTF) of the liquid crystal adaptive optical system is almost the same as the diffraction limited.MTF 0.4@50 lp/mm.The limited resolution of the CCD is 31 lp/mm
we could see that the resources of CCD has been used effectively.The focal length of the whole optical system is 19.9m and the F number is 16.The peak-valve(PV) value is 0.0314.
