Development of Arc induced Surface Degradation Evaluation System ofSolar Array by an optical Microscope

摘要

The system which scans and inspect surface of asolar array coupon panel automatically wasdeveloped. This system is composed of an opticalmicroscope, traverse equipment, a personalcomputer and a picture acquisition board. Thissystem can acquire the microscope photograph withhigh magnification and observe from a slant angle.Detail scan of a solar array was carried out beforeand after plasma experiment. Dust particles werediscovered at several arc locations.
