FRINGE PROJECTOR FOR DEPTH SENSING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18088302 titled 'FRINGE PROJECTOR FOR DEPTH SENSING
Simplified Explanation
The optical system described in the patent application is designed for eye tracking operations in a head-mounted device. The system includes a transparent layer, a laser, and two output couplers that are in the field of view of the user. The laser emits light into the transparent layer, and the output couplers out-couple different portions of the light to generate a fringe pattern on the user's eye.

Original Abstract Submitted
An optical system is configured to support eye tracking operations in a head mounted device. The optical system includes a transparent layer, a laser, and first and second output couplers. The laser is configured to emit light into the transparent layer. The first output coupler is configured to out-couple a first portion of the light from a first location of the transparent layer. The second output coupler is configured to out-couple a second portion of the light from a second location of the transparent layer. The first and second output couplers are in the field-of-view of a user. A combination of the first portion of the light and the second portion of the light out-coupled from the first output coupler and the second output coupler is configured to generate a fringe pattern, for example, on an eye of a user of the head mounted device.
