US7964841 Patents
The present image display device is an image display device that scans laser beams emitted from light sources 101, 102 and 103 to form an image on a projection surface, and includes laser beam diameter-converting optical systems 104 that shape a beam waist of a laser beam, and horizontal scanner 106 and vertical scanner 107 for scanning a laser beam. Beam diameter-converting optical systems 104 adjust the beam diameter at the position of mirror 26, which is a beam deflector for scanner 106 and 107, to be smaller than the
