Sum modified-Laplacian(SML) operator has been proposed as focusing measuration to measure the relative sharpness of image sequence that captured from microscope at different distance to locate the height of surface of wear debris, and reconstruct the 3D image of wear-debris.

Near-field optical microscopy, based on scanning sample surfaces by the tip of optical probe, obtained the imagined information about the object surface.

In this thesis, by using time-resolved small angle light scattering and optical microscopy, the phase separation of hollow glass beads filled polystyrene and poly (vinyl methyl ether) blends are studied.

Studies on Mechanisms of Stabilizers and Antifoggants on AgCl Microcrystal by the Method of Chemical Microscopy;

Morphology of pollen grains of 36 species belonging to 16 sections from Camellia was examined under light microscope.

The appearance of laser scanning confocal microscope result in dramatic improvements in real-time dynamics of living tissues and cells,optical sectioning,there-dimensional reconstruction of these sections comparing with light microscope.

This study compared the results of fiber analysis by light microscope from different laboratories, in order to investigate the analyzing accuracy of light microscope for the slurry compositing wood with nonwood materials.
