A projection optical system applicable to a head-up display device mounted on an automobile includes an image generation unit, a reflection unit, a double-telecentric lens, a light splitting device, and an imaging lens that are successively arranged in a light exit direction. The light splitting device needs to be arranged on an image side of the double-telecentric lens and configured to reflect a light beam for imaging in light beams emitted by the image generation unit. The double-telecentric lens is configured to adjust a size of the projection image. The imaging lens is configured to adjust a virtual image distance of the projection image and output the light beams of the projection image to achieve projection imaging.
