Optical imaging apparatus

Abstract

The present disclosure provides an optical imaging apparatus, including: a first optical element including an image projection component and a first positioning component that are integrally formed, a second optical element including a beam splitting component and a second positioning component that are integrally formed, and a third optical element including a reflective component and a third positioning component that are integrally formed; structures of the first positioning component, the second positioning component, and the third positioning component cause the image projection component, the beam splitting component, and the reflective component achieve optical alignment according to desired optical accuracy index requirements. In the apparatus described above, respective elements are assembled based on their respective positioning components without aid of other components, which reduces difficulty of mounting among respective elements and simplifies the mounting process. Meanwhile, the positioning component in each element is integrated with other components, which further reduces the mounting error among the respective elements, thereby further improving mounting accuracy of the optical system.
