摘要： An illumination optical system for a beam projector includes: a light source; a color conversion unit having at least one fluorescent substance layer that reflects a light from the light source or converts the light emitted from the light source to a wavelength-converted light; and a dichroic mirror that causes the light emitted from the light source to be incident on the color conversion unit. Lights reflected or emitted by the conversion unit and having different wavelengths are incident on a display panel through the same path. In the illumination optical system, a light emitted from one light source can be processed to produce red, green and blue lights which can be in turn incident on the display panel through the same optical path of the light reflected or emitted by the conversion unit.

摘要： A method and a portable terminal for identifying a counterfeit bill. The method includes receiving, by the portable terminal, an image of a bill photographed using visible rays and an image of the bill photographed using infrared rays; determining a denomination of the bill by comparing the image photographed using the visible rays with a denomination database; obtaining correction information using the image photographed using the visible rays and a corresponding bill image in the denomination database; forming a corrected image by correcting the image photographed using the infrared rays using the correction information; and determining whether the bill is counterfeit by comparing the corrected image with an image of the corresponding bill pre-stored in a genuine bill database.
