Abstract: A spectroscopic measurement device includes a light receiving element that receives light and outputs a light receiving signal, a variable amplification circuit that amplifies the light receiving signal which is input, and a dark voltage correction unit that calculates a correction coefficient that is a rate of change of a dark voltage value with respect to gains, based on an output value of the variable amplification circuit with each value of two or more gains which are equal to or greater than a predetermined value in an environment where no light is incident on the light receiving element.

Abstract: An optical module includes a variable wavelength interference filter provided with a pair of reflecting films, and an electrostatic actuator configured to change a gap dimension between the pair of reflecting films, a driver configured to apply a periodic drive voltage to the electrostatic actuator, a gap detector configured to detect a gap dimension between the pair of reflecting films, and a light receiver configured to receive light from the variable wavelength interference filter. The light reception signal from the light receiver is detected at a predetermined timing from a detection timing of one of a maximum value and a minimum value of the gap dimension detected by the gap detector.

Abstract: A printer includes a printing section that ejects an ink, and a spectrometer that disperses incident light. The spectrometer includes a window section that transmits the light, an optical filter device, and a light receiving section. The optical filter device includes a variable wavelength interference filter as a dispersing element that disperses light transmitted by the window section. The light receiving section receives the light which is dispersed by the variable wavelength interference filter. A dirtiness of the window section is detected based on measured values corresponding to each of a plurality of wavelengths obtained by spectrally measuring light from a reference object, and reference values corresponding to each of the plurality of wavelengths.

Abstract: A printer moves a color chart relative to a spectrometer that carries out spectral measurement on the color chart. The color chart, which is a color measurement target of the printer, includes a color patch and a white portion that is positioned in a first position and a second position. The first position and the second position interpose a color measurement position, in which the color patch is disposed, along a predetermined direction. The printer acquires measured values by carrying out spectral measurement for the color measurement position, the first position, and the second position, determines a reference value corresponding to the color measurement position based on the measured values of the first position and the second position, and determines a color measurement result of the color patch based on the measured value of the color measurement position and the reference value.
