Title:
ULTRAVIOLET FLUORESCENT COLOR DETECTION DEVICE AND ULTRAVIOLET FLUORESCENT COLOR DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/173210
Kind Code:
A1
Abstract:
Provided are an ultraviolet fluorescent color detection device and an ultraviolet fluorescent color detection method capable of simply and accurately detecting the reading accuracy of a visible fluorescent color of a medium during irradiation with ultraviolet light. Ultraviolet rays are radiated to the medium from an ultraviolet light source (a first light source unit (4)). A white LED light source (a light source included in a second light source unit (3)) emits white light by causing fluorescence of a fluorescent substance. Light that has passed through at least one visible light color filter is incident on a plurality of light receiving elements provided in a light receiving unit. An output signal from each light receiving element obtained when the fluorescent light from the medium irradiated with the ultraviolet light from the ultraviolet light source is incident on the plurality of light receiving elements through the visible light color filter is corrected on the basis of output signals from the light receiving elements obtained when the light from a white reference material (200) irradiated with white light from the white LED light source is incident on the plurality of light receiving elements through the visible light color filter.
