Abstract: 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.

Abstract: 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.

Abstract: An object of the present invention is to provide a spectral characteristic measuring system, a spectral characteristic measuring instrument, a data processing apparatus, and a program, which make it possible to appropriately correct an influence of an illumination light variation caused by a temperature rise in a semiconductor light-emitting element due to light emission, in a scanning type color measurement system or the like which sequentially measures many color samples 1n and in which a semiconductor light-emitting element such as an LED is used as a light source and a reference system is not provided.Spectral distributions of illumination lights which are measured before and after the color sample is measured are interpolated, to thereby estimate a spectral distribution of an illumination light at the time when a spectral distribution of the color sample is obtained. Spectral characteristics of the color sample are identified based on the spectral distribution of the reflected light or the transmitted light reflected by or transmitted through the color sample and the estimated spectral distribution.

Abstract: In a wavelength displacement correcting system and method of the invention, a monochromatic beam from a light emitting diode driven by a constant current is incident through an incident slit of a spectral device. The incident beam is diffracted on a diffraction grating to form a dispersed light image, and information relating to the dispersed light image of the incident slit is outputted from the spectral device. A wavelength displacement amount of the monochromatic beam is calculated, using a forward voltage value corresponding to the constant current, and a forward voltage initial value. Wavelength displacement amounts of at least two diffracted beams are calculated, using output values of the at least two diffracted beams, and diffracted beam output initial values with respect to the dispersed light image. A dispersion width displacement amount of the spectral device is calculated, using the calculated wavelength displacement amount of the monochromatic beam, and the calculated wavelength displacement amounts of at least two diffracted beams, whereby a wavelength displacement of the spectral device is corrected.
