Abstract: A projector including a light source, a light valve, a projection lens and a displacement module is provided. The light source generates an illumination light. The light valve converts the illumination light into a multi-pixel area image light. The projection lens is disposed in a transmission path of the multi-pixel area image light. The image displacement module includes a carrier, an optical element, a frame and a base. The carrier, the frame and the base are substantially coplanar with each other, and the multi-pixel area image light provided is configured to be moved by the optical element and being moved along a third direction in response to the spinning of the carrier, and the first direction is different from the second direction. Furthermore, a three-dimensional printing apparatus is also provided.

Abstract: A light path adjustment mechanism includes a bracket, a light valve, a carrier, a first axis, a second axis and an optical plate member. A surface normal of a surface of the light valve crosses the bracket to define an intersection closest to the surface of the light valve, and the bracket has an end point furthest from the intersection measured in the direction of the surface normal. A distance between the intersection and the surface measured in the direction of the surface normal is smaller than a distance between the intersection and the end point measured in the direction of the surface normal.

Abstract: An image displacement module is adapted for an optical apparatus to switch image positions of a plurality of plane image. The image displacement module includes a carrying base and a rotating base. The carrying base is adapted to control the rotating base to vibrate back forth within an angle, such that the imaging positions of the plane image on the horizontal direction are moved by a first distance and the imaging positions of the plane image on the vertical direction are moved by a second distance at the same time. Alternatively, the carrying base is adapted to control the rotating base to rotate relative to two axes of a reference plane, such that the plane image are moved by a distance along one of a plurality of movement directions.
