Abstract:
An image projector for forming a visible image on an object, said image projector comprising:a light beam projector that projects two light beams; and a deflector that changes frequently a proceeding direction in which the projected light beams proceed so as to change rapidly and repeatedly positions of first and second surface areas on the object, that are irradiated simultaneously by the projected light beams and that are spaced apart from one another, to form the visible image on the object, whereby the two light beams are arranged as staggered relative to an imaginary substantially straight line as seen in the proceeding direction so that the resultant light beam formed by the two beams together is long-and-narrow shaped as seen in the proceeding direction to irradiate simultaneously the surface areas spaced apart from each other along the imaginary substantially straight line on the object as seen in the proceeding direction.
