A projection optical system applicable to a head-up display device mounted on an automobile includes an image generation unit, a first reflection unit, a double-telecentric lens, a light splitting device, a first lens, a second reflection unit, and a second lens that are successively arranged in a light exit direction; and a controller connected to the image generation unit and the light splitting device. The light splitting device with sector shape top view arranges on an image side of the double-telecentric lens. When the image generation unit emits a first image, the light splitting device swings to a first angle, such that the first image is emitted and imaged through the first lens and when the image generation unit emits a second image, the light splitting device swings to an initial position, such that the second image is emitted and imaged through the second lens.
