| Research Abstract |
New techniques of quantitative analysis of rock textures using a laser scanning microscope (LSM) are proposed. A LSM equipped with polarized filters was used to capture various kinds of digital images of rock texture. Confocal images of reflected laser beams were used to analyze surface topography of rock specimens. Cracks and grain boundaries in rocks were cleary visualized and analyzed by digital image processing techniques. Polarized images of rock textures under blue (B=488 nm), green (G=568 nm) and red (R=633 nm) laser beams were superimposed to construct color (RGB) images. Optical properties of minerals such as reflectance and retardation are accurately measured by the LSM.Spectroscopic imaging of rock texture enable us to viusalize the distribution of a mineral under considerlation. Organic materials in sedimentary rocks are detected in intensity of map of fluorescence.
