Method for viewing invisible indicia |
摘要 |
A method for detecting and viewing invisible indicia includes illuminating the invisible indicia with radiation of a first wavelength with an illumination source; detecting emitted light from the invisible indicia at a second wavelength with a sensor array; eliminating reflected radiation at the first wavelength; focusing an image of the invisible indicia on the sensor array; displaying the image of the invisible indicia; spacing the sensor array at a fixed distance from the invisible indicia with a spacer; and adjusting sensitivity of the sensor array. |
