摘要： The DRAW type optical recording medium which can record optical information by forming information pits in the recording layer by irradiation of an energy beam such as laser beam, and yet can reproduce the information immediately after writing without requiring any step of developing processing after writing of information. The optical recording medium includes a recording layer (3) for forming information pits through the occurrence of physical deformation by irradiation of an energy beam and a sensitizing layer (4) for augmenting the physical deformation in the recording layer (3) laminated on a support (2). By the presence of the sensitizing layer, recording sensitivity is improved and also stability of the medium with lapse of time becomes excellent. Further, due to the presence of the sensitizing layer, the optical recording medium can be a sealed structure and therefore the optical recording medium is lightweight and flexible, and can be made in various forms such as card, sheet, a flexible sheet, and the like.

摘要： A method and apparatus for measuring surface roughness, waviness, cracks or any irregularities or flatnesses in a surface utilizing statistical properties of dichromatic speckle patterns. In practice surface roughness is normally measured utilizing standard profile measuring devices. However, these instruments are not efficient in practice in view of their slowness for effecting measurements. The present invention provides an improved method of measuring surface roughness including the following steps; generating a spatially coherent polychromatic light having at least two wavelengths and directing the light at an optically rough surface in order to illuminate the same; analyzing intensity variations in two speckle patterns formed at a plane due to two wavelengths of the polychromatic light; and defining and evaluating a difference between intensities of the two speckle patterns as a function of surface roughness of the optically rough surface.

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.
