<P>PROBLEM TO BE SOLVED: To provide an art of giving various meanings to a display form of a visible-light laser in the visible-light laser beam irradiation system for irradiating a part of a vehicle interior of the vehicle with the visible-light laser in order to provide an occupant with information. <P>SOLUTION: The visible-light laser beam irradiation system mounted on the vehicle is equipped with the laser irradiation device, for irradiating the vehicle interior of the vehicle with the visible-light laser, and a control device for controlling a diffusion rate of a beam of the visible-light laser irradiated by the laser irradiation device, the control device chooses the first diffusion rate under the first condition, furthermore, controls the laser irradiation device so that the diffusion rate of the beam, irradiated by the laser irradiation device, becomes the first diffusion rate, and, chooses the second diffusion rate different from the first diffusion rate under the second condition different from the first condition, and, furthermore, controls the laser irradiation device so that the diffusion rate of the beam irradiated by the laser irradiation device becomes the second diffusion rate. <P>COPYRIGHT: (C)2011,JPO&INPIT |
