Claim:
1. An autostereoscopic projection device, comprising: a light source module providing a light; a light scanning module including an actuating device and a reflective surface, and the actuating device capable of deflecting the reflective surface; a light transmitting module; a light combining module including a first light combining element; a spatial light modulator module including a first spatial light modulator element, wherein the normal vector of an incident surface of the first light combining element is coplanar with the normal vector of a reflective surface of the first spatial light modulator element, and the coplanar plane is perpendicular to a disposition plane of the projection device; and a lens, wherein the light provided by the light source module is transmitted through the light scanning module, the light transmitting module, the light combining module and the spatial light modulator module sequentially and then leaves the projection device through the lens, wherein the light transmitting module is a reflective mirror disposed between the light combining module and the light scanning module, wherein the light of the light source module on the X-Y coordinate plane transmitted along the Z-axis direction is transmitted to the Y-Z coordinate plane by the light scanning module so as to be scanned and imaged on the Y-axis direction, and is further transmitted to the X-Z coordinate lane by the light transmitting module so as to be scanned and imaged on the X-axis direction.
