Embodiment Construction
[0035] Such as Figure 1-3 As shown, an augmented reality head-up display system includes a projection module 11 , an imaging element 12 , an optical flat mirror 13 , a concave mirror 14 and a holographic optical film 15 .
[0036] The projection module 11 is used to project light, which is arranged obliquely upward, and the projecting direction is obliquely upward. The source image is projected onto the imaging element 12 through the projection module 11 .
[0037] In this embodiment, the projection module 11 adopts a laser projection module, which can provide higher brightness than LED, and has the advantages of good monochromaticity and coherence, and the surface brightness loss is relatively small when the picture is enlarged.
[0038] The imaging element 12 and the flat optical mirror 13 are sequentially arranged on the projection path of the projection module 11 .
[0039] The imaging element 12 is used to allow the light to pass through to form a real image and form a ...
