摘要: 在航空和汽车等领域，抬头显示技术(Head-Up Display, HUD)的应用日益广泛。鉴于现代社会用眼负荷增加，本研究针对青少年近视问题，提出了一种具有大视场角、低畸变特性的抬头显示系统设计方案。该系统设计考虑了8米远的投影距离，旨在通过减少用眼负担来预防近视的发展。同时考虑到自由曲面在光学设计中高度的设计自由度，以及其对畸变的有效控制，对系统进行了进一步优化。本文通过光学设计软件Code V进行设计与优化，所设计的两版系统在成像性能上均满足了既定要求，全视场角达到30˚，同时将畸变控制在5%以内。此外，本研究还涉及了样机的制造和实际体验测试，以验证所提出设计方案的可行性。通过实际应用测试，进一步证实了该抬头显示系统设计的有效性和实用性，为未来相关技术的发展和应用提供了科学依据和实践指导。
Abstract: In the fields of aviation and automobiles, the application of Head-Up Display (HUD) is becoming more and more extensive. In view of the increasing eye load in modern society, this study proposes a design scheme of a head-up display system with a large field of view and low distortion characteristics for the problem of juvenile myopia. The system design takes into account the projection distance of 8 meters away, aiming to prevent the development of myopia by reducing the burden on the eye. Considering the high degree of design freedom of freeform surface in optical design and its effective control of distortion, the system is further optimized. In this paper, the optical design software Code V is used for design and optimization. The two designed versions of the system meet the established requirements in terms of imaging performance. The full field of view angle is up to 30˚, and the distortion is controlled within 5%. In addition, this study also involves prototype manufacturing and actual experience testing to verify the feasibility of the proposed design. Through the practical application test, the effectiveness and practicability of the design of the head-up display system are further confirmed, which provides a scientific basis and practical guidance for the development and application of related technologies in the future.
