Title:
2次元走査装置及びそれを用いた走査型画像表示装置
Document Type and Number:
Japanese Patent JP4522109
Kind Code:
B2
Abstract:
The optical scanning apparatus of the present invention is an optical scanning apparatus for scanning a surface to be scanned with light from a light source, provided with a deflecting optical system for deflecting a beam from a light source optical system in a first scanning direction and a second scanning direction orthogonal to the first scanning direction, and a scanning optical system including at least one reflecting surface of a non-rotation symmetrical shape, and for directing the deflected beam deflected by the deflecting optical system onto the surface to be scanned by the use of the aforementioned at least one reflecting surface of a non-rotation symmetrical shape, wherein the principal ray of the beam incident on the center of the angle of view of the surface to be scanned is incident while being inclined with respect to the surface to be scanned in at least the first scanning direction of the first and second scanning directions.
