Analyzing characteristic of the cube-corner retroreflector applied to laser straightness measurement;

By vector analysis the rectangular angle error influence on characteristics of the beam of cube-corner retroreflector;

Then,the effect on the first-harmonic nonlinearity by the polarization properties of reflected light of the cube-corner retroreflector and axial rotation in the motion direction of the measurement cube-corner retroreflector is derived.

Gonioscopy after cataract phacoemulsification and PC-IOL implantation through sutureless corneoscleral tunnel incision;

MethodsFifty eyes from 45 patients with anterior chamber angles closure estimated by gonioscopy were observed using UBM,including 5 eyes with neovascular glaucoma,22eyes with acute angle-closed glaucoma and 23eyes with chronic angle-closure glaucoma.

ObjectIn this thesis paper we try to make a detailed portray to the anterior chamber angle in the surgery eyes suffering from PACG after successful trabeculectomy in order to better understand the state of the illness after trabeculectomy and as a control to the gonioscope examination of the failed cases.

Method for correction of barrel distortion due to wide-angle lenses based on a polynomial;

In order to correct the barrel distortion of wide-angle lens, a new method based on spline function was proposed.

In the film and television works,the wide-angle lens participation is indispensable.

An innovative gain module is employed to improve the performance of heat-conduct cooled asymmetric laser,which consists of a Nd∶YAG rod pumped by a semicylidrically arranged LD array,and right-angle prism as the mirror,leading to a highly stable output with a high quality.

The automatic test of Corner Cube Reflector (CCR), Roof Prism and Right-angle Prism is achieved by calculating the wavefront got from the digital phase-shifting interferometer.
