An optical system for stereoprojection comprises an object image (101) and a projection object lens (102). The optical system is provided with a transmission light path and a reflection light path. A polarization beam splitter and a first liquid crystal variable phase retarder (107) are provided in the transmission light path, and the polarization beam splitter, a first lens or lens group (108), a second lens or lens group (109), a plane mirror (110) with an image inversion function and a second liquid crystal variable phase retarder (111) are provided in the reflection light path, wherein the polarization beam splitter comprises a first triangular prism (103), a second triangular prism (104), first flat glass (105) and second flat glass (106). A method for carrying out the stereoprojection is also provided. |
