Title:
LASER PROJECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/098278
Kind Code:
A1
Abstract:
A laser projection apparatus, comprising a light source (101), an optical machine (102), and a lens (103). The optical machine (102) comprises a light guide pipe (1022), a lens component (1023), a reflecting mirror (1024), a prism component (1026), and a digital micromirror device (1025). The optical axis of an illumination beam transmitted by the light guide pipe (1022) and the lens component (1023) serves as a first optical axis (I-I). The optical axis of an illumination beam reflected by the reflecting mirror (1024) to the prism component (1026) serves as a second optical axis (II-II). The first optical axis (I-I) is perpendicular to the second optical axis (II-II), and both of the first optical axis (I-I) and the second optical axis (II-II) are parallel to a light receiving surface (1025a) of the digital micromirror device (1025).
