==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.
