An optical measuring instrumentis equipped with an optical systemto be used for measuring a characteristic of the aqueous humor in the anterior chamberof an eyeballof a measurement subject person and a holding unitwhich holds the optical systemetc. The optical systemis equipped with a light emitting systemA and a photodetecting systemB. An optical pathis set so that light emitted from the light emitting systemA passes through (traverses) the anterior chamberand is detected by the photodetecting systemB in a state that the eyeballis turned outward.

Eyeball optical measuring instrument, eyeball optical measuring method, and method for irradiating an eyeball and detecting light coming from eyeball

An optical measurement apparatus includes: an emission section that emits light such that the light travels across an anterior chamber of an eyeball of a measurement subject; a light reception section that receives light that is emitted from the emission section and travels across the anterior chamber; and a positioning section that performs positioning of one of the emission section and the light reception section at a position where skin on a periphery of an inner canthus of the eyeball is squeezed into an eye socket accommodating the eyeball.

A concentration calculation system calculates a concentration of the optically active substance based on a formula. The formula includes a first function representing wavelength dependence of an optical rotation of a first optically-active substance, and a second function representing wavelength dependence of an optical rotation of a second optically-active substance. In the first function, concentration of the first optically-active substance has an unknown value, and an inherent value for defining a characteristic of optical rotatory dispersion of the first optically-active substance is a known value or an unknown value within a certain limited range. In the second function, an inherent value for defining a characteristic of optical rotatory dispersion of the second optically-active substance is an unknown value. The concentration of the first optically-active substance is calculated based on the formula and optical rotations of measurement target respectively corresponding to a plurality of wavelengths, by using a least-squares method.

An image forming apparatus includes an image forming device forming an image on a recording medium; and a light source that, after the image has been formed by the image forming device, irradiates the recording medium with light to fix the image on the recording medium, while the recording medium moves relatively in a predetermined movement direction. The light source includes a current supply section, a light emitting section, and a current output section. Current for light emission is supplied to the current supply section. The light emitting section includes light emitting elements that are disposed two-dimensionally. At least the light emitting elements provided side by side in the movement direction are electrically connected in parallel. The current output section outputs the current that has passed through the light emitting section. The current supply section and the light emitting section are provided side by side in the movement direction.
