METHOD FOR FORMING VISIBLE IMAGE IN SPACE BY USING PLURALITY OF LASER BEAMS

摘要

PROBLEM TO BE SOLVED: To provide a new and useful method to form a visible image in a desired space by using properties of laser beam. SOLUTION: The method for forming a visible image in a desired space is carried out by irradiating a desired space with a plurality of laser beams having different wavelengths from different positions to cross one another in the desired space so that energy is superimposed and colors are changed in the crossing part of the laser beams.
