Research and development on optical fiber panel shadow defects automatic detection system

Optical fiber panel is used more and more widely as a key component of contemporary electron optical imaging devices.In accordance with the national standard which stipulates the method in the shadow defects inspection,researches are carried out to develop an automatic system with which the shadow defects can be tested effectively.The edges of the shadow defects can be detected and optimized by improving CANNY OPERATOR and detection of the defects can go automatically by the organic integration and overall control of the software system as well as the hardware system.At last,through the corresponding calculation method,the main features,parameters and indexes of the shadow defects are offered;at the same time,the quantitative analysis of it is also achieved.The results of these experiments have shown the advantages of this automatic system,which is easy to operate,quick and accurate to process data,stable and reliable in performance.The system is valuable in practice.
