A new nondestructive technique, confocal scanning laser microscopy (CSLM), is described which is used to characterize the topography and morphology of polymer coatings. The topography of the coating can be determined even when the coating is completely opaque. When the coating is not completely opaque, CSLM has the distinct advantage of also being able to distinguish between the coating surface...

Optical technologies are being used increasingly to perform real-time assessment of tissue abnormalities. Many groups have demonstrated that quantitative optical spectroscopic approaches, including fluorescence spectroscopy1-4 and reflectance spectroscopy,5, 6 have the potential to deliver a highly sensitive, specific, and costeffective diagnosis in real time and without the removal of tissue. ...

introduction: the aim of this study was to investigate the scanning electron microscope (sem) analysis of tooth surface irradiated by different parameters of er:yag laser. methods: 15 caries-free extracted human third molars were used in this study. the teeth were put into 5 groups for laser irradiation as follows: group 1 (power: 2.5 w, energy: 250 mj); group 2(power: 3 w, energy: 300 mj); gro...

Confocal scanning optical microscopy (CSOM) is a new optical microscopic technique, which offers significant advantages over conventional microscopy. In laser scanning optical microscopy (SOM), the specimen is scanned by a diffractionlimited spot of laser light, and light transmitted or reflected by the in-focus illuminated volume element (voxel) of the specimen, or the fluorescence emission ex...
