AI Technical Summary
⚠Technical Problem
Small-sized optical imaging systems in portable terminal devices struggle to image objects at a distance, especially due to limited installation space, making it difficult to increase the focal length ratio.
⚗Method used
The system employs a multi-lens structure, including a lens design with reflective and refractive areas. By combining the first to fourth lenses, specific optical condition expressions are satisfied to increase the focal ratio and improve imaging capabilities without increasing the overall system length.
🎯Benefits of technology
It achieves a fourfold increase in focal length without increasing the overall length of the optical imaging system, making it suitable for portable terminal devices and improving long-distance imaging capabilities.
