AI Technical Summary

⚠Technical Problem

Existing virtual reality systems struggle to accurately receive both real-world and virtual images simultaneously when simulating human eye imaging, resulting in an unnatural and uncomfortable visual experience.

⚗Method used

Design a human eye-inspired wide field-of-view optical lens, including an optical system composed of negative and positive lenses. It simulates the human eye in structure and function, has an 80° field of view and a total length of 23mm, and uses cemented connections between lenses to reduce light scattering. It is equipped with an infrared cut-off filter and image plane protection glass to meet specific focal length and refractive index conditions.

🎯Benefits of technology

It achieves a wide field of view for natural visual perception, improves image clarity and contrast, reduces light energy loss, and can simultaneously receive external information and virtual images, facilitating research on improvements to virtual reality systems.
