The invention discloses a head-up display optical system for expanding a viewing angle by adopting an array mirror mode. The system at least comprises an automobile windshield, a curved mirror, a spectroscope I, a spectroscope II, a spectroscope III, a luminous source, an eye box and a virtual imaging position; the head-up display optical system is used for reducing the size and adopting an arraylens design mode, the reflectivity of the first spectroscope, the reflectivity of the second spectroscope and the reflectivity of the third spectroscope are R1, R2 and R3 respectively, the penetrationrate of the first spectroscope, the penetration rate of the second spectroscope and the penetration rate of the third spectroscope are T1, T2 and T3 respectively, R1 is larger than R2 larger than R3and T3 is larger than T2 larger than T1; an imaging light path of the head-up display optical system comprises an upper viewing angle path, a middle viewing angle path and a lower viewing angle path.According to the head-up display optical system, a spectroscope array lens design mode is adopted, image display of three light paths of an upper view angle, a middle view angle and a lower view anglecan be achieved, then large view angle expansion of a head-up display is achieved, and the definition of the head-up display optical system is high.

    一种采用阵镜方式进行视角扩展的抬头显示光学系统。它至少包括汽车挡风玻璃、曲面镜、分光镜一、分光镜二、分光镜三、发光源、眼盒、成虚像位置;所述抬头显示光学系统为用于缩小体积且采用阵镜设计方式的抬头显示光学系统,所述分光镜一、二、三的反射率分别为R1、R2、R3,所述分光镜一、二、三的穿透率分别为T1、T2、T3,则满足:R1>R2>R3,且满足:T3>T2>T1;所述抬头显示光学系统的成像光路包括上视角路径、中视角路径、下视角路径。该抬头显示光学系统采用分光镜阵镜设计方式,能实现上视角、中视角、下视角三种光路的图像显示,进而使得抬头显示器实现较大的视角扩展,同时抬头显示光学系统清晰度高。
