An adaptive optics imaging system is introduced in this paper. A high-resolution liquid crystal on silicon (LCOS) device was used as a phase-only wavefront corrector instead of a conversional deformable mirror. The wavefront aberration was detected by a Shack-Hartmann (SH) wavefront sensor, which has a wavefront measurement accuracy of λ/100 rms (λ = 0.6328 μm). Under this construction, Peak-to-Valley correction precision of 0.09 λ was reached. Furthermore, some low-frequency hot convection turbulence induced by an electric iron was compensated in real time at the same precision. The modulation transfer function (MTF) of this system was also measured before and after wavefront correction. Under the active correction of LCOS, the system reached the diffraction limited resolution approximately 65l p/mm on the horizontal direction. All of this showed the possibility of using this device in a high-resolution, low temporal turbulence imaging system, such as retinal imaging, to improve the resolution performance.
