Title:
PORTABLE ULTRAVIOLET EXCITED FLUORESCENCE INTENSITY DETECTOR
Document Type and Number:
WIPO Patent Application WO/2017/206942
Kind Code:
A1
Abstract:
Portable ultraviolet excited fluorescence intensity detector (100) and method of the same are provided. The detector for carrying out quantitative fluorescence detection for a disposable hygiene product's raw materials, comprising a housing (200), wherein a detection opening is formed in a planar sidewall of the housing (200), an ultraviolet emitting light path, a first receiving light path and a second receiving light path are defined within the housing (200) such that these light paths are coplanar, wherein after the portable ultraviolet excited fluorescence intensity detector is placed on a planar substrate to be tested, the ultraviolet emitting, first receiving and second receiving light paths converge at a point in a surface of the planar substrate, wherein an ultraviolet source (911) is arranged in the ultraviolet emitting light path and is adapted to emit ultraviolet light towards the point and excite fluorescence there, a first sensor (921) and a second sensor (931) are arranged within the first receiving light path and the second receiving light path respectively such that the sensors can be selectively operated, wherein the first sensor is designed to convert light, whose wavelength is between 420 and 480 nm, into electric signals proportional to the light intensity, the second sensor is designed to convert light, whose wavelength is between 480 and 760 nm, into electric signals proportional to the light intensity, and wherein a first filter device and a second filter device are allocated to the first and second sensors respectively such that the excited fluorescence can be received by the first and second sensors through the first and second filter devices respectively.
