PIXEL SHIFTING DEVICE AND PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18393912 titled 'PIXEL SHIFTING DEVICE AND PROJECTOR
The pixel shifting device described in the abstract consists of a first frame holding an optical member that oscillates around a first axis, a second frame oscillating around a second axis, a base coupled to the second frame, first and second actuators for oscillating the frames, and various coupling parts and shaft formation parts.
- The device includes a first frame with an optical member and a second frame, both oscillating around different axes.
- A base is coupled to the second frame via a coupling part.
- The first and second frames are connected by shaft formation parts.
- First and second actuators are used to oscillate the frames.
- The second frame and base have extending parts along the second axis, where the second actuator is located.
- The shaft formation parts have coupling parts and beams extending along the second axis.
