The multi-focal plane display system includes a laser projection optical engine and a holographic reflection light fusion device. The laser projection optical engine is configured to generate and modulate at least two laser beam groups, and transmit the at least two laser beam groups to the holographic reflective optical fusion device, where each laser beam group corresponds to one displayed image. The holographic reflective optical fusion device is configured to reflect the at least two laser beam groups, where exit pupil locations of the at least two laser beam groups are the same, and displayed images of at least two focal planes are obtained by performing imaging on the at least two laser beam groups by a human eye. A structure of the multi-focus plane display system provided in the embodiments is easy to implement."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-focal plane display system and device","description":"A multi-focal plane display system and a device are provided.
