Embodiment Construction

[0015] The present invention overcomes the above-discussed safety issues by providing a detection device that prevents a user from irradiating their eyes with ultraviolet light of an intensity that can cause eye damage. now refer to figure 1 , which illustrates one embodiment of a fluorescence detection system according to the present invention. The detection system 10 includes a UV light source 12 and a fluorescence detector 14 . The bank note 15 to be scanned is passed through the detector in a direction perpendicular to the plane of the drawing. Detection system 10 includes housing 16 that prevents ultraviolet light generated by light source 12 from reaching the user's eyes.

[0016] The ultraviolet light source 12 is preferably a light emitting diode emitting ultraviolet light. The light source 12 preferably emits ultraviolet light in a wavelength range of 350 to 400 nm.

[0017] Detector 14 includes a filter 17 and one or more photodetectors 18 sensitive to light in t...

Abstract

The invention discloses a hand-held fluorescence detector, which comprises: a hand-held data process system and an ultraviolet source connected to data process system. Wherein, the ultraviolet source radiates the scanned object with ultraviolet wavelength; the safe device prevents the light of ultraviolet source reach the eye with harmful strength; the fluorescence detector senses the fluorescence of object that responding the radiation. The inventive fluorescence detection can utilize optical-electric detector or human watcher; the detector can be mounted in beehive telephone or PDA. And thesafe device uses baffle plate or total internal reflection to protect the user. It also can be combined with a cross-line device which can avoid opening ultraviolet source when there is no object.

Description

technical field [0001] The present invention relates to a portable fluorescence detection unit suitable for eye protection. Background technique [0002] Many detection challenges rely on sensing fluorescent dyes excited by UV light. For example, many countries utilize currency with fluorescent dyes to make it more difficult to counterfeit the currency. The dyes are arranged in a special pattern and are visible with the aid of ultraviolet light. Furthermore, different denomination banknotes have different dyes and / or dye patterns to further prevent counterfeiting of larger denomination banknotes by printing them on the paper used for smaller denomination banknotes. Vending machines often have fluorescent imaging systems to determine the authenticity of currency that has been placed into the machine. Similarly, banks have scanners for detecting counterfeit bills. [0003] Ultraviolet light-emitting diodes (UV LEDs) are now available, whereby, in principle, inexpensive, co...
