Device Alignment Systems - A simplified explanation of the abstract
This abstract first appeared for US patent application 18444945 titled 'Device Alignment Systems
Simplified Explanation:
This patent application describes a head-mounted device with display projectors that use waveguides to convey images to eye boxes. Optical couplers like prisms couple the images into the waveguides, which guide them to output couplers for viewing by the user. Sensor circuitry measures misalignment between optical components, and control circuitry repositions them using actuators to correct misalignment.
- Key Features and Innovation:
- Head-mounted device with display projectors. - Use of waveguides to convey images to eye boxes. - Optical couplers like prisms for coupling images. - Sensor circuitry for measuring misalignment. - Control circuitry for repositioning optical components.

Original Abstract Submitted
A head-mounted device may have display projectors that provide images. Waveguides may be used in conveying the images to eye boxes. Optical couplers such as prisms may be used to couple the images from the projectors into the waveguides. The waveguides may guide the images to output couplers that couple the images toward eye boxes for viewing by a user. During operation of the head-mounted device, sensor circuitry may be used to measure for potential misalignment between optical components such as projectors, couplers, and waveguides. Control circuitry may provide control commands to zero hold power piezoelectric actuators or other positioners based on the sensor measurements, thereby tilting and otherwise repositioning the optical components relative to each other to correct for optical component misalignment.
