Optical image measuring device

An optical image measuring device comprising:

• an optical system including separating and image forming means and optical characteristics selecting means;
• and
• single imaging means for capturing a plurality of images obtained by means of said optical system, simultaneously or virtually simultaneously;
• wherein said separating and image forming means separates a single image to be detected into a plurality of images which are formed on a single imaging means;
• said optical characteristics selecting means selectively extracts an optical characteristic with respect to at least one image of said plurality of images;
• and
• the single imaging means detects the plurality of separately formed images, respectively and separately.

An optical image measuring device comprising:

• single imaging means;
• a combination of optical elements forming a plurality of light paths which separate a single image to be detected onto a single imaging means, forming images thereof in the same imaging direction;
• and
• a wavelength selecting element positioned in at least one of the light paths, for selecting a particular wavelength component;
• wherein said single imaging means detects a plurality of images including different wavelength components obtained by separating the single image to be detected.

A measurement method wherein light is irradiated onto an organism, the light emitted from the organism is detected by a two-dimensional detector, and biological information is measured using the detected images;

• comprising the steps of:
• obtaining measurement image data for a plurality of pixels of an organism using a plurality of measurement wavelengths;
• and reference image data for at least one pixel using the same measurement wavelengths as the aforementioned measurement wavelengths;
• and
• deriving two-dimensional information for absolute quantities relating to biological information by performing calculation based on the difference of said measurement image data and reference image data for each measurement wavelength.

An optical biological measurement device for irradiating light onto an organism, detecting the light emitted from the organism by a two-dimensional detector, and measuring biological information by means of the detected image;

• comprising:
• image measuring means for measuring two-dimensional measurement image data for the organism using a plurality of measurement wavelengths;
• and
• image calculating means, having reference image data for at least one pixel obtained using the same measurement wavelength as said measurement wavelength, for determining two-dimensional information for absolute quantities relating to biological information, by performing calculation based on the difference of said measurement image data and reference image data for each measurement wavelength.
