A system includes a light outputting element configured to output a first beam propagating toward a beam interference zone from a first side of the beam interference zone. The system also includes a reflective assembly configured to reflect the first beam back as a second beam propagating toward the beam interference zone from a second side of the beam interference zone. The first beam and the second beam interfere with one another within the beam interference zone to generate a polarization interference pattern.

System and method for fabricating liquid crystal polarization holograms

A system includes a mask configured to forwardly diffract an input beam as a first set of two polarized beams. The system also includes a polarization conversion element configured to convert the first set of two polarized beams into a second set of two polarized beams having opposite handednesses. The two polarized beams having opposite handednesses interfere with one another to generate a polarization interference pattern.

System and method for fabricating polarization holograms

A system includes a diffractive optical element configured to receive a first beam and a second beam interfering with one another to generate a first interference pattern. The diffractive optical element is also configured to forwardly diffract the first beam and the second beam to output a third beam and a fourth beam. The third beam and the fourth beam interfere with one another to generate a second interference pattern. The system also includes a detector configured to detect the second interference pattern.

System and method for interference fringe stabilization

A display device includes a display, an optical assembly, and a display-moving assembly connected to the display for moving the display between a first position and a second position. When in the first position, the display outputs image light in a first direction substantially parallel to an optical axis of the optical assembly. When in the second position, the display is positioned away from the optical axis of the optical assembly. The display device also includes a partial reflector and a partial reflector-moving assembly connected to the partial reflector for moving the partial reflector between a third position and a fourth position. When the partial reflector is in the third position, the display is in the first position and the display is disposed between the optical assembly and the partial reflector. When the partial reflector is in the fourth position, the display is in the second position.

Head-mounted display device with a flip-up display

A display device includes a frame, a display, an optical assembly, and a display-moving assembly connected to the display and the frame. The display-moving assembly is configured to move the display between multiple different positions, including a first position and a second position. When the display is in the first position, the display is configured to output image light in a first direction. The first direction is substantially parallel to an optical axis of the optical assembly. When the display is in the second position, the display is positioned away from the optical axis of the optical assembly.

A biopsy device handle having a biased firing mechanism activated by side and rear triggers. The firing mechanism has a longitudinally sliding deflecting portion including a post. The post is disposed within a channel and retained by a catch. The deflecting portion deflects transversely when transverse force is applied to a transverse face by the side trigger or when a longitudinal force is applied to an inclined face by the rear trigger to release the post from the catch.
