Design of a large field of view light engine for augmented reality displays

In recent years, augmented reality (AR) optical technology has become a prominent focus in the field of optics. For near-eye display technology, achieving miniaturization and a large field of view (FOV) are critical objectives. And the compact design of the large FOV projection optical engine is essential for the miniaturization of the overall module. The system design, illumination uniformity analysis, and stray light evaluation were conducted. Finally, a prototype was fabricated.
