Optical sectioning imaging technology and its application in industrial detection and science research

Two optical sectioning imaging technologies with visible laser and near infrared laser illumination to apply industrial and biologic detection are presented respectively in this paper. One of them is based on fiber optical confocal scanning microscopy, the other is imaging-relay arrangement with small visible field. The systems have resolution of submicron at lateral direction and nanometer resolution in axial direction and wider work range about submillimeter magnitude.
