OPTICAL SCANNING DEVICE AND TWO-DIMENSIONAL IMAGE DISPLAY DEVICE USING THE SAME |
摘要 |
An optical scanning device capable of stably and uniformly performing linear optical scanning by using a high-brightness light source is provided. The device includes: at least one laser light source (11) for emitting a laser light; a deflection section (15) for deflecting and scanning the laser light emitted from the at least one laser light source (11); and a light guide plate (17) of which a side surface is irradiated with the laser light deflected and scanned by the deflection section (15). The at least one laser light source (11) includes a multi-mode fiber light source, or a broad-stripe semiconductor laser light source arranged such that a vertical direction of a stripe structure is parallel to a scanning direction. An exit pupil in a thickness direction, which is perpendicular to the scanning direction, is formed at least in one area on the side surface of the light guide plate (17).
