CAS Changchun Institute of Optics, Fine Mechanics, and Physics has recently rolled out a

high definition eyeground image compensator that has passed experts' approval. With a

compensation resolution of 3 microns and a depth of 10 microns, the new instrument is

able to perform no-injury imaging tests on highly advanced short-sighted patients.

Researchers realized the self-adaptive depth compensation, using a deformable mirror

correction technique, taking into account the optical properties of both human eyeground

and laser source. In the course of working on a simple, convenient, safe, and evenly

distributed eyeground imaging system, researchers have produced 5 invention patents,

and 16 papers on the technology.
