CALIBRATION METHOD OF PORTABLE DETECTOR WHICH IS USED TO DETECT NEAR-INFRARED PHOSPHOR AND PORTABLE DETECTOR WHICH IS USED TO DETECT NEAR-INFRARED PHOSPHOR FOR FORGERY DISCRIMINATION
PURPOSE: A near-infrared light emitting body recognizing device for distinguishing whether paper money is faked and a measuring method thereof are provided to increase result reproducibility and increase measurement sensitivity of a probe unit. CONSTITUTION: A probe controller(11) compares information of a sample inputted from the outside with existing information and transmits the comparison result to an external device. A light source(12) is connected to a probe controller. The light source emits light of a specific wavelength and irradiates the light on a sample on a printed material(30). A light source stabilizer(14) is connected to the light source and the probe controller to regularly control output of the light source. A filter unit(40) passes only light of a fixed range of wavelength emitted from the sample.
