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: A light detection sensor includes a light source that irradiates a detection target with light, a rod lens that collects emitted light from the detection target, a first light receiving element that detects the emitted light that has passed through the rod lens, and a second light receiving element that detects the emitted light that has passed through the rod lens, at a position different from a position at which the first light receiving element detects the light.

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: A paper sheet recognition apparatus (1) that recognizes a paper sheet based on an optical spectrum acquired from the paper sheet includes, a light source unit (31) including light sources arranged corresponding to 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 of light received by the light receiving surface, a memory (80) that stores an optical spectrum measurement condition, and a light-source control unit (72) that controls the light source unit (31) based on the optical spectrum measurement condition. The optical spectrum measurement condition includes information for identifying at least one light source corresponding to the predetermined partial area, information for identifying a timing for turning on the identified light source, and information for identifying a timing for turning off the light source.

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.
