Abstract

The invention discloses a portable fluorescence coding detection device. The portable fluorescence coding detection device comprises an upper housing and a lower housing; a USB interface, an indicating lamp, a digital display screen, a switch button and a signal processor are integrated on a circuit board; a focusing lens is arranged in the lower housing; a sealing ring is installed between the focusing lens and the circuit board; an LED light source and a photoelectric detector are integrated on the circuit board; the photoelectric detector is connected with the signal processor; and the lower housing is provided with a battery bin which is electrically connected with the circuit board. The portable fluorescence coding detection device is small in size and convenient to carry, and has thecharacteristics of rapidness, accuracy, portability, wide range and programmability; the device is provided with a plurality of LED excitation light sources and a photoelectric detector, and can quickly detect and judge near-ultraviolet to near-infrared multi-band fluorescence information emitted by a detected object; and programming setting can be carried out for corresponding fluorescence codesso as to adapt to different detection materials and methods.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a portable fluorescent code detection device. Background technique [0002] Fluorescent materials have long been used as the main anti-counterfeiting technology on cards and tickets because of their concealment and easy identification. A common fluorescent anti-counterfeiting solution is to add ultraviolet fluorescent ink to paper and other anti-counterfeiting materials. After being irradiated by ultraviolet lamps, the fluorescent spectrum in the visible band can be excited. The human eye can distinguish the authenticity by identifying the hue and shape of the fluorescent light. Although this identification method is simple, it also has many problems. [0003] First of all, the human eye's recognition accuracy of color and intensity is not accurate enough, and it is difficult to distinguish spectra with similar wavelengths or light intensities, so it is impossible to a...
