Abstract

An augmented reality (AR) head-up display (HUD) system based on holographic optical elements (HOEs) with multiple depths, large area, high diffraction efficiency and a single picture generation unit (PGU) is proposed. Since HOEs has excellent wavelength selectivity and angle selectivity, as well as the ability to modulate complex light waves, HOEs can image the red, green and blue parts of the color image emitted by PGU on different depth planes. The experimental results show that the three HOEs of red, green, and blue clearly display images at different depths of 150cm, 500cm, and 1000cm, and the diffraction efficiencies are 75.2%, 73.1%, and 67.5%, respectively. The size of HOEs is 20cm×15cm. In addition, the field of view (FOV) and eye-box (EB) of the system are 12°×10° and 9.5cm×11.2cm.
