Abstract

The application discloses a HUD (head up display) imaging system, a realization method, and a HUD. The HUD imaging system comprises a picture generation unit (PGU) adopting a laser light source; a picture imaging unit for processing a projection picture of the laser source; and a holographic optical element HOE adopting a reflective holographic transparent material. The technical problem that theHUD imaging system is low in light energy utilization rate and high in power consumption is solved. The reflectivity or the light energy utilization rate of the imaging system can be obviously improved through the HUD imaging system in the application. Furthermore, the HUD imaging system can guarantee the high transmission of a combiner in a CHUD or windshield in a WHUD while reducing the power consumption.

Description

technical field [0001] The present application relates to the fields of optics and digital data processing, in particular, to a HUD imaging system, an implementation method, and a HUD. Background technique [0002] Head-up display (full name in English: head up display, abbreviated as: HUD) first appeared on fighter jets. In order to prevent pilots from frequently looking down at the instruments to concentrate, important information is displayed on a piece of transparent glass in front of the line of sight. According to different display screens, HUD can be divided into CHUD (Combiner-HUD, combined head-up display) and WHUD (Windshield HUD windshield-type head-up display). [0003] The inventors have found that a reflective combiner (combiner) is used in the Combiner-HUD to realize image amplification and reflection. Windshield-HUD uses windshield glass and free-form mirrors to achieve image magnification and reflection. That is to say, both Combiner-HUD and Windshield-HUD...
