The invention discloses an
air suspension imaging optical
system based on polarized
light control and a reflection optical structure. The
air suspension imaging optical
system comprises an image source
assembly; a polarization light splitting module, a polarization state conversion module and a reflection module;
linearly polarized light emitted by the image source
assembly is sequentially reflected or transmitted by the polarization
beam splitting module, enters the polarization state conversion module to change the polarization state, is focused by the reflection module, returns, is converted into
linearly polarized light through the polarization state conversion module again, and is transmitted or reflected through the polarization
beam splitting assembly. A
naked eye visible suspension
real image without a physical medium is formed in the imaging area; through the above structure, the image light realizes high-efficiency light path turn-back and direction selection through a polarization control path, high-luminous-efficiency and high-quality
aerial imaging is realized, and finally, an aerial
real image which is visible to naked eyes and free of a medium is formed at a specific spatial position in the air; the
system does not need to depend on a traditional imaging medium, and has the advantages of compact structure, high luminous efficiency
utilization rate and good imaging brightness and definition.
