    Abstract: Die Strömungsrate eines lichtstreuenden Fluids wird leichter und schneller gemessen.Ein Strömungsraten-Messverfahren gemäß der vorliegenden Offenbarung weist Folgendes auf: Erzeugen von wenigstens zwei Specklebildern durch kontinuierliches Abbilden eines zu messenden lichtstreuenden Fluids, während eine Zeit, die kürzer als die Zeit bis zum Verschwinden der räumlichen Korrelation ist, welche der Zeit entspricht, in der die räumliche Korrelation zwischen vom lichtstreuenden Fluid erzeugten Specklemustern verschwindet, als Belichtungszeit definiert wird, bei einem Zeitintervall, das kürzer als die Zeit bis zum Verschwinden der räumlichen Korrelation ist, und Berechnen der Richtung und der Geschwindigkeit der Strömung des lichtstreuenden Fluids anhand einer zeitlichen Variation der Specklemuster zwischen den wenigstens zwei Specklebildern, wobei die Specklebilder unter Verwendung einer Abbildungsvorrichtung, an der ein Flächensensor angebracht ist, und einer Pixelgruppe eines Teils des Flächensensors oder unter Verwendung einer Abbildungsvorrichtung, an der ein Liniensensor angebracht ist, erzeugt werden.

    Abstract: A magneto-optic recording and reproducing medium is formed of a reproduction layer composed mainly of GdFeCo and having a saturation magnetization of at least 450 emu/cc and a coercive force of not more than 4 kOe, and a recording layer composed mainly of TbFeCo, having a coercive force of at least 5 kOe, and having a magnetization of not more than 300 emu/cc when it is a transition metal-predominant film and not more than 200 emu/cc when it is a rare earth-predominant film.

    Abstract: A method and apparatus for recording and reproducing information onto and from a magneto-optic recording medium is disclosed. The magneto-optic recording medium has at least a reproducing layer and a recording layer. A recording optical head records information on the magneto-optic recording medium. A reproducing optical head has a reading light beam for reading information recorded in a region within a spot of the reading light beam by magneto-optic effect by changing a state of magnetization of the reproducing layer and at the same time irradiating the recording medium with the light beam. A wavelength of the recording light beam emitted by the recording optical head is substantially smaller than a wavelength of the reading light beam emitted by the reading optical head. A minimum ratio of the wavelength of the recording light beam to that of the reproducing light beam is 1:3.

    Abstract: A fluorescence life measuring apparatus, a fluorescence life measuring method and a program that can obtain fluorescence life using a simple configuration are proposed. The apparatus moves a stage on which a fluorescent material to be measured is placed, irradiates with excitation light the fluorescent material placed on the stage moved at a constant speed, images afterglow of emitted fluorescence caused by the excitation light, and uses an imaged image to detect the elapsed time from a fluorescence position and afterglow strength at a target afterglow position and calculate the fluorescence life.

    Abstract: A method and apparatus for recording and reproducing information onto and from a magneto-optic recording medium (100) is disclosed. The magneto-optic recording medium (100) has at least a reproducing layer (110) and a recording layer (130). A recording optical head (51) records information on the magneto-optic recording medium (100). A reproducing optical head (61) has a reading light beam for reading information recorded in a region within a spot of the reading light beam by magneto-optic effect by changing a state of magnetization of the reproducing layer (110) and at the same time irradiating the recording medium (100) with the light beam. A wavelength of the recording light beam emitted by the recording optical head (51) is substantially smaller than a wavelength of the reading light beam emitted by the reading optical head. A minimum ratio of the wavelength of the recording light beam to that of the reproducing light beam is 1:3.
