摘要： A measurement controller is electrically connected with light emitting circuits and controls the light emission of light sources. A calculator calculates reflection characteristic measurement values of a measurement object corresponding to the respective illuminators. Undetermined coefficients of a Gaussian function stored in a memory are determined using the calculated reflection characteristic measurement values, and errors created by an angle of inclination of a normal to a surface of the measurement object with respect to a center axis of a main body are corrected using the Gaussian function whose undetermined coefficients are determined to obtain corrected reflection characteristic values. Since a measurement result is corrected according to the angle of inclination of the main body with respect to the object surface, this enables a high-precision colormetry.

摘要： An ellipsoidal mirror having an axis of rotational symmetry is disposed so that a first focal point thereof is positioned in vicinity of a measurement area of a light source to be measured. The ellipsoidal mirror reflects parallel light beams from the measurement area onto an optical focal plane on which the reflected light beams are focused, whereby a luminous intensity distribution image of the measurement area is formed on the optical focal plane. The luminous intensity distribution image is directed via a relay lens system onto a sensing surface of an image pickup unit. A distribution of luminous intensity of the measurement area is obtained based on the luminous intensity distribution image.

摘要： An optical analyzer such as oximeter is provided including a source of light having a plurality of different wavelengths. At least two or more of the different wavelengths have a fixed relationship of light absorption after coaction with hemoglobin oxide. The light is directed at the subject tissue and received after coaction by an optical probe. A first signal representative of the degree of light absorption at a predetermined standard wavelength is determined and then an attempt is made to match a second wavelength having a fixed relationship of light absorption to the predetermined standard wavelength, e.g., equal absorption, to generate a second signal representative of the second wavelength, whereby the amount of hemoglobin oxide can be determined in the bloodstream.

摘要： An eye fundus plethysmograph assembly is provided for determining variations in the amount of blood present at the fundus of the eye. A source of at least a first and second wavelength of light energy is specifically directed into a subject eye for reflection from the retina or fundus of the eye. The reflected light is directed at a receiving element that can produce a first output signal representative of a reflected first wavelength and a second output signal representative of a reflected second wavelength. A processing circuit is provided for subtracting one of the first and second output signals from the other to provide a representative measurement output of the amount of blood in the blood vessels adjacent the eye fundus. The output signals can be recorded or displayed in any desired form to facilitate the interpretation of the amount of blood present.

摘要： Wavelength information indicating a correspondence relationship between a plurality of light receiving elements of a light receiving unit and wavelengths of pieces of lights is stored. First and second intensity distributions of the light related to first and second dispersion images are acquired based on a signal outputted from each of the light receiving elements when a monochromatic light is passed through a opening of a light shielding body and first and second dispersion images related to primary and secondary diffracted light are formed on the light receiving unit. An estimated intensity distribution of the light related to the second dispersion image is calculated from the first intensity distribution according to a predetermined relational expression. A change amount related to the wavelength information is calculated based on the estimated intensity distribution and the second intensity distribution. The wavelength information is corrected according to the change amount.

摘要： A light receiving optical system includes: a relay optical system for converging light to be measured which has been converged on an image plane of an objective optical system. The light receiving optical system has a relay optical system with a relay lens operable to be selectively switched between first and a second conjugate positions, and a first and a second light flux limiting aperture members selectively switched between the first and the second conjugate positions. The relay optical system selectively forms, on the image plane of the objective optical system, an enlarged image and a reduced image of a view angle defining aperture in the case where the relay lens is selectively switched between the first and the second conjugate positions to define an incident light flux through the view angle defining aperture by a first and a second light flux limiting apertures, respectively.
