  • Publication number: 20130100449
    Abstract: Light irradiates one light incident position on the surface of a scattering-absorption body. The light that propagates through the interior of the scattering-absorption body is detected at one light detecting position on the surface of the scattering-absorption body. On the basis of a light detection signal, a temporal profile of the light intensity of the detected light is acquired, and on the basis of the temporal profile, an mean optical path length of the light in the interior of the scattering-absorption body and information relating to the amount of substance to be measured in a region to be measured are calculated. The information relating to the amount of substance to be measured is corrected on the basis of the mean optical path length, such that the longer the mean optical path length, the greater the amount of substance to be measured is.

  • Patent number: 8422127
    Abstract: The present invention relates to a microscopic image capturing apparatus having a structure that, in scanning an imageable area of an imaging unit in a predetermined direction in an imaging object area, in which a sample is present, can reliably set a focal point of the imaging unit on each imaging position set inside the imaging object area regardless of the type of focusing actuator. The microscopic image capturing apparatus has a sample setting stage having a sample setting surface that is inclined with respect to a scan plane orthogonal to an optical axis of an objective lens. By moving the sample setting stage along the scan plane such that the distance in the optical axis direction between the imaging unit and the sample setting surface varies monotonously, the focal point position of the imaging unit is adjusted in only one direction along the optical axis of the objective lens.
