摘要： In the channeled spectroscopic polarimetry, a measurement error of a parameter showing a spectropolarization characteristic of a sample is effectively removed, the error being generated by various variations in retardation of a retarder depending upon the state of the sample. With attention being focused that the retardation of the retarder may be kept constant by stabilization of an incident direction of light that transmits through the retarder, the retarder was arranged on the light source side with respect to the sample so as to effectively remove an influence relative to a measurement error, such as variations in direction of a light ray due to the sample.

摘要： The blood flow is examined by making multifractal analysis of a blood flow velocity distribution in a vascular network and detecting a deviation of the blood flow velocity distribution from the multifractal distribution. The blood flow velocity distribution is provided as an image by irradiating laser light to the vascular network, converging, by an imaging lens, scattered laser light rays by blood cells in the blood flowing through blood vessels, detecting, by a photodetector, a speckle pattern produced owing to random interference between the scattered laser light rays and calculating the rate of change with time lapse of each speckle in the speckle pattern.
