摘要： A spectrum measuring device including a ribbon element, a light detection element, and circuitry. The ribbon element includes a first light reflector including a plurality of first light reflection surfaces configured to be translated in an out-of-plane direction, and a second light reflector including a plurality of second light reflection surfaces that are fixed. The circuitry supplies a drive signal to the ribbon element in such a manner that a change of a displacement amount difference between the first light reflection surfaces and the second light reflection surfaces corresponds to a predetermined frequency; and acquires the light quantity data detected by the light detection element at a predetermined sampling frequency.

摘要： (Object) To enable to provide a small-scale and low-cost spectrometer (Means of Achieving the Object) A spectrometer includes: a light incidence unit configured to allow incidence of light from outside; a diffraction grating configured to disperse, according to wavelength, the light that is incident through the light incidence unit; and a reflection unit including a reflection surface for reflecting the light that has been dispersed according to wavelength by the diffraction grating. Tilt of the reflection surface is changeable.

摘要： A movable diffraction element and a spectroscope. The movable diffraction element includes a movable component having a comb-like shape, a supporting unit configured to support the movable component, a first cantilever actuator coupled to the supporting unit, a displacement determiner coupled to an edge of the first cantilever actuator, and a second cantilever actuator disposed parallel to the first cantilever actuator. In the movable diffraction element, a slope generated when the second cantilever actuator deforms is approximately equivalent to a slope generated at the first cantilever actuator. The spectroscope includes the movable diffraction element.

摘要： A frame, a spectroscope, a spectrometry unit, and an image forming apparatus. The frame has hollow structure and includes at least four apertures including a first aperture, a second aperture, a third aperture through which light enters the frame, and a fourth aperture, a concave diffraction grating disposed at a position of the first aperture, and a movable reflector disposed at a position of the second aperture to reflect light dispersed by the concave diffraction grating and change a reflection angle of the reflected light. Through the fourth aperture of the frame, the light reflected by the movable reflector exits the frame. The spectroscope includes the frame, and the frame further includes an optical entrance disposed at a position of the third aperture, and an optical exit disposed at a position of the fourth aperture.

摘要： A spectral measurement device includes a light reflection grating having a plurality of movable gratings and a movable grating drive unit that displaces the movable gratings to alter a grating pattern of the light reflection grating, a light detecting element that detects light incident on the light reflection grating, a storage unit storing a relationship between a light quantity to be detected by the light detecting element and corresponding light intensities at differing wavelengths for different grating patterns, and a computation unit that calculates light intensities at the differing wavelengths of the light incident on the light reflection grating based on the light quantity of the incident light detected by the light detecting element for each of the different grating patterns by altering the grating pattern based on the relationship between the light quantity and the corresponding light intensities for the different grating patterns stored in the storage unit.
