A dual-liquid light valve single-projector stereo projection system, including along the optical path direction successively: a projector (1), a linear polarizer (2), a first optical self-compensation curved liquid light valve (3), a second optical self-compensation curved liquid light valve (4), a polarization state converter (5), a projection screen (6), a pair of circular polarization glasses (7) and a synchronization circuit (8). Since two self-compensation curved liquid light valves are employed, the present invention can adjust the polarization state of the light at a high speed, realizing stereo projection with a high frame rate, and the stereo projection system is simple in structure, low in costs, and high in image quality.
