Abstract: A light detection sensor 10 comprises a light source 12 for radiating light to a detection object T and a light receiver 11 comprising a plurality of detectors for detecting intensity of light from the detection object T. The plurality of detectors comprises at least, a first detector 11a for detecting intensity of light of a first wavelength band, and a second detector 11b for detecting intensity of light of a second wavelength band different from the first wavelength band. Sensitivity of the first detector 11a to the light of the first wavelength band is lower than sensitivity of the second detector 11b to the light of the second wavelength band. A light receiving area of the first detector 11a is larger than a light receiving area of the second detector 11b.

Abstract: A fluorescence and phosphorescence detection device includes a fluorescence and phosphorescence sensor, a data acquiring unit, and an emission detection unit. The fluorescence and phosphorescence sensor includes a light source that emits an excitation light of a predetermined wavelength, and a photodetection unit that detects fluorescence emission and phosphorescence emission excited from the paper sheet by the excitation light. The data acquiring unit acquires a time-series waveform of a signal outputted from the fluorescence and phosphorescence sensor in response to the detection of the emission in the photodetection unit. The emission detection unit detects the fluorescence emission from the time-series waveform of a period in which the excitation light is emitted from the light source and detects the phosphorescence emission from an attenuation curve appearing on the time-series waveform of a period in which emission of the excitation light from the light source is stopped.

Abstract: An aim is to reduce the size of an optical sensor which detects radiated light such as phosphorescence radiated from a detection target excited by exciting light, and to increase a radiated light receiving surface of the optical sensor. An optical sensor is configured to be provided with: a light source which irradiates excitation light; a light detector which detects radiation light emitted from a detection target excited by the excitation light; and a single light guide unit which guides the excitation light to the detection target and guides the radiation light to the light detector.

Abstract: In order to efficiently acquire an optical characteristic from partial areas on the paper sheet, a paper sheet recognition apparatus (1) that recognizes a paper sheet by using an optical spectrum acquired from the paper sheet on a transport path (60) includes, a light source unit (31) including light sources arranged corresponding to the partial areas on the paper sheet, a reading unit (32) having a light receiving surface to receive reflected lights from the partial areas, a sensor unit (34) that acquires an optical spectrum from light received by the light receiving surface, a memory (80) that stores an optical spectrum measurement condition for acquiring an optical spectrum from a predetermined partial area on the paper sheet. The optical spectrum measurement condition includes information for identifying at least one light source corresponding to the predetermined partial area among the light sources of the light source unit (31), information for identifying a timing for turning on the identified light source, and information for identifying a timing for turning off the light source turned on at the timing for turning on; and a light-source control unit (72) that controls the light source unit (31) based on the optical spectrum measurement condition.

Abstract: A paper sheet authentication apparatus determines the type of the paper sheet by using a characteristic other than a fluorescent light characteristic, sequentially emits excitation lights of different wavelengths on the paper sheet, measures an intensity of light per wavelength within a predetermined range emitted by a fluorescent material applied to the paper sheet, and acquires fluorescent light characteristic data as the result. The paper sheet authentication apparatus performs the authentication of the paper sheet by using fluorescent light characteristic data of a genuine paper sheet previously stored per type of the paper sheet or a threshold calculated therefrom and the acquired fluorescent light characteristic data.
