Abstract
An adaptive optical objective inspection instrument for optic nerve function comprises: a sub-system for measuring wave aberration of human's eyes, including a near infrared beacon light source, an intermediate optical system, a wavefront corrector and a wavefront sensor, configured to measure and obtain wave aberration of testee's eyes, the intermediate optical system arranged along an optical path between the near infrared beacon light source and the wavefront sensor, and the wavefront corrector arranged in the optical path of the intermediate optical system; a sub-system for correcting wave aberration of human's eyes, including the intermediate optical system, the wavefront corrector and a control unit, the control unit configured to drive and control the wavefront corrector to correct the wave aberration of testee's eyes according to the measured wave aberration; and a sub-system for inspecting optic nerve function, including a visual stimulus display and a system for collecting visual evoked potential signal.
