摘要

摘要在汽车领域使用基于激光的照明系统进行信息投影,以增强道路用户之间的通信,这引起了人们的极大兴趣。到目前为止,已经报道了使用折射和反射光学器件的基于激光的前端投影的大量工作,而对于后端照明,由于体积大小和视场调节有限,需要不同的光学设计概念。在这里,我们报告了一种用于汽车应用的基于激光的后端照明系统的新的通用方法,该方法能够投影信息或信号以支持其他道路用户。该设计基于在照明时投影所需图案的薄衍射光学元件。此外,为了保护道路使用者免受转向激光束的影响,设计了一个漫射背投影屏幕来投影信息,同时满足视野和安全要求。投影系统基于由尺寸在毫米范围内的双锥透镜阵列制成的周期性漫射结构。模拟透镜阵列的视场(FOV)符合欧洲经济委员会(ECE)设定的角度要求。作为概念的证明,扩散屏幕是使用微制造技术制造的,并进行了表征。未来,屏幕将与薄衍射光学元件相结合,实现整个集成投影系统。

Diffractive optics based automotive lighting system
Abstract Information projection using laser-based illumination systems in the automotive area is of keen interest to enhance communication between road users. Numerous work on laser-based front end projection employing refractive and reflective optics has been reported so far, while for rear end illumination efforts are more scarce and a different optical design concept due to limited volumetric size and field of view regulations is required. Here, we report on a new and versatile approach for a laser-based rear end lighting system for automotive application which enables projection of information or signals to support other road users. The design is based on thin diffractive optical elements projecting the desired patterns upon illumination. Also, for protection of the road users from the steering laser beam, a diffusive back projection screen is designed to project information while fulfilling both the field of view and safety requirements. The projection system is based on a periodic diffusive structure made of an array of biconic lenses with sizes in the millimeter range. The field of view (FOV) from the simulated lens arrays complies with the angular requirements set by the Economic Commission for Europe (ECE). As a proof of concept, the diffusive screen is fabricated using microfabrication technology and characterized. In future, the screen will be combined with thin diffractive optical elements to realize an entire integrated projection system.
