Abstract
Disclosed is an optical apparatus including a display unit, a lens configured to pass an image formed by and transmitted from the display unit, a base configured to accommodate the lens therein, and an adjustment unit configured to move the lens relative to the base so as to adjust a path of light passing through the lens.
Claims18
An optical apparatus comprising:
- a display unit;
- a lens having a first protrusion and a second protrusion and configured to pass an image formed by and transmitted from the display unit, and transmitting light having any one of a p-wave and a s-wave;
- a base having a guide hole and configured to accommodate the lens therein;
- and
- an adjustment unit configured to move the lens relative to the base so as to adjust a path of light passing through the lens;
- wherein the adjustment unit is configured to be movable in a first direction such that the lens is movable relative to the base in a second direction perpendicular to the first direction,
- wherein the lens is movable relative to the base by moving an adjustment lever, and
- wherein the base includes a first indentation configured to accommodate at least a portion of the adjustment lever or the first protrusion therein, the first indentation communicating with the guide hole, and a second indentation configured to accommodate at least a portion of the second protrusion therein.

An optical apparatus comprising:
- a lens having a first protrusion and a second protrusion and transmitting light having any one of a p-wave and a s-wave;
- a base having a guide hole and configured to accommodate the lens therein;
- and
- an adjustment lever having one end coupled to the lens and an opposite end exposed outside the base, the adjustment lever being configured to be movable in a first direction such that the lens is movable relative to the base in a second direction perpendicular to the first direction to adjust a path of light passing through the lens;
- wherein the lens is movable relative to the base by moving the adjustment lever, and
- wherein the base includes a first indentation configured to accommodate at least a portion of the adjustment lever or the first protrusion therein, the first indentation communicating with the guide hole, and a second indentation configured to accommodate at least a portion of the second protrusion therein.
3 more elements
An optical apparatus comprising a housing configured to change a path of light of an image emitted from a display device so as to provide an observer with the resulting image,
- wherein the housing comprises:
- a reflective surface configured to reflect light emitted from the display device;
- and
- a mirror in contact with the reflective surface and inclined relative to the reflective surface by a prescribed angle so as to vertically emit the light reflected from the reflective surface to an outside, and
- wherein the housing has a holographic optical element including a high refractive index material and a low refractive index material, which are alternately formed in a horizontal direction on the reflective surface.
