<p>A dual-chip beam splitting and combining module (100) comprises a beam splitting prism (10), a first reflector (21), a first polarized total internal reflection prism (22), a first display chip (23), a second reflector (31), a second polarized total internal reflection prism (32), a second display chip (33), and a beam combining beam (40). The dual-chip beam splitting and combining module splits incident non-polarized light into first polarized light and second polarized light, and combine the first polarized light and the second polarized light. Also provided is a 3D optical projection system comprising the dual-chip beam splitting and combining module. When a dual-chip structure of a microelectromechanical lens system is used, the 3D function can be achieved at the refresh frequency of above 60 Hz, which greatly lowers the requirements of the 3D function on the refresh frequency of the display chip, and also improves the utilization of light. Moreover, since the same optical projection lens and light source lens are adopted, convenient calibration and simple structure are achieved.</p> |
