A projection system is provided, and includes: a phase compensation apparatus (101), configured to perform first phase compensation and chromatic aberration correction on a light ray of a received image, and reflect an output light ray of the image to a holographic combiner (102); and the holographic combiner (102), configured to perform second phase compensation on the light ray that is of the image and that is output by the phase compensation apparatus (101). The phase compensation apparatus (101) is utilized to correct at least one of the following aberrations: astigmatism, a spherical aberration, and a coma aberration; and further correct another aberration in combination with the holographic combiner (102), thereby effectively eliminating aberrations and improving imaging quality. The projection system is used in a head-up display system, an augmented reality display system, a head-mounted display device, and the like.
