摘要
A portable detector for special wavelength and a detection method using the same are provided to sense special luminous body, which is excited by ultraviolet ray or visible ray to emit near-field infrared ray, regardless of place and power supply. A portable detector for special wavelength comprises a light source(15) radiating light of special wavelength to illuminate a sample of prints, a light source stabilizer(16) which keeps the output of the light source uniform, the prints(50) in which the sample emitting light of special wavelength is printed, a long pass filter(14) which filters the light of special wavelength so that only a specific wavelength range of the light is passed, a detection unit(13) which receives the light of the filtered wavelength and transmits it to an amplifier, an A/D converter(11) converting analog signal into digital signal, the amplifier(12) which amplifies the transmitted signal and sends it to the A/D converter, an information display(20) which indicates the light signal of the special wavelength on a screen, and a controller(10) which compares the sample information with the existing information and outputs it through the information display.
