Light and thin type optical module and VR equipment |
| abstract |
The invention discloses a light and thin optical module and VR equipment, the optical module includes lens unit, first polarization piece and first phase delay piece between the first polarization piece and the lens unit; the light rays incident from one side of the lens unit are folded back among the lens unit, the first phase delay piece and the first polarizer and finally emitted to human eyes from the first polarizer; the incident light is circularly polarized light or elliptically polarized light; the optical module further includes: the phase compensation unit is arranged between the first polarization piece and the first phase delay piece and is used for correcting the phase; alternatively, the tolerance epsilon of the first phase delay element satisfies: and | < lambda/36, where lambda is the wavelength of the incident light. The optical module provided by the invention solves the problem that the viewing experience of a user is influenced by unexpected incidence to human eyes due to phase errors, and improves the viewing experience of the user. |
