“…This method can easily balance the residual aberration. Qin et al [28] used a picture generation units(PGU) and a curved mirror to perform imaging separately to obtain two focal planes, and optimized the optical design and mechanical structure. Kim et al [29] used a cylindrical lens as an asymmetric aberration corrector to obtain a corrected linear astigmatism and spherical aberration optical system.…”

A novel optical-transmission rear mounted augmented reality head-up display, which can be used to improve the safety of a driving vehicle, is introduced and investigated in this paper. The proposed system uses an off-axis free-form mirror that serves as asymmetric aberration corrector. The off-axis aberration of the system is analyzed and the mirror is designed to correct both linear astigmatism and spherical aberration. This makes it possible to optimize the whole optical system. We also analyze the relationship between human eyes and the virtual image to obtain a registration matrix. The experimental results show that the size of the virtual image is 11 inches, the imaging distance is 2.8 meters, and the area of the eye box is 140 * 60 mm 2. The novel system makes it possible to fuse the virtual image with the real-life scene to improve driver safety.

“…The optical system of HUDs is mainly implemented in three ways: the reflection scheme with freeform mirrors, the waveguide scheme, and the holographic scheme [2][3][4]. Nowadays, the developing freeform optics technology allows the reflective HUD based on geometric optics to eliminate aberrations with one freeform component effectively [2]. Waveguide HUDs are based on total internal reflection and light coupling components, easily achieving large FOV [3].…”

“…Although dual focal planes can be easily obtained by this approach, it introduces several drawbacks such as increased cost, reduced reliability, and expanded volume, making AR-HUDs unavailable in compact cars [6]. Further, to develop an AR-HUD using a single PGU and a single freeform mirror, Qin et al [2] proposes to divide a single PGU into two logically separated parts and optically relay one of them to a new position to create two focal planes. In this manner, the expanded volume of AR-HUDs is addressed while the resolution of the PGU is halved.…”

The combination of augmented reality (AR) and head‐up display (HUD) makes HUD more and more attractive in recent years. In this paper, we propose a dual‐focal‐plane windshield‐type AR‐HUD prototype using a single freeform mirror, then fold the light path by polarization‐related elements to realize a compact volume using a single picture generation unit (PGU). The designed system meets the design specifications with experimental verification.

“…BOE has proposed the use of two PGUs to achieve a multi-depth heads-up display [1], and Yi-Pai Huang et al have used a single LCD as a PGU with an absorption wall to achieve two images [2], but these two methods are expensive to develop and require a freeform mirror and more optical mirrors. Huan Chen's team proposed the use of a CGH head-up display [3], but this method can only present images on a single focal plane.…”

The application of CGH display technology to AR multi‐depth head‐up displays is a very popular research topic nowadays. However, the system implementation requires multiple projection devices or spatial light modulators with Freeform Mirror or complex optical mechanisms to present multi‐depth projection of automotive head‐up display, which does not meet the development needs in terms of system size and cost. Thus, it is worthwhile to investigate how to realize a multi‐depth projection head‐up display system with a single spatial light modulator. In this study, we attempt to realize a miniaturized multi‐depth CGH head‐up display system with Space‐Division Method (SDM) and a single spatial light modulator.
