A touch screen device includes a transmitter optical fiber, optical transmitter circuitry, a receiver optical fiber, optical receiver circuitry, and cover material. The transmitter optical fiber and/or the receiver optical fiber include a respective core, a respective absorptive clad circumferentially surrounding the respective core, and/or a respective absorptive jacket circumferentially surrounding the respective absorptive clad.

One disclosed embodiment includes techniques for temperature-dependent reference image correction in structured light projectors that may be used for generating three-dimensional (3D) scene depth maps. The techniques disclosed herein include receiving an indication of a temperature (e.g., an actual current operating temperature or a change in the current operating temperature relative to an established reference temperature) associated with one or more components of a projector and then determining, based on the temperature indication, an amount of adjustment needed to correct a reference pattern image based on an estimated effective focal length change of the projector. Next, a reference pattern image may be appropriately adjusted, e.g., based on the determined amount of effective focal length adjustment caused by the current operating temperature of the projector, to generate a corrected reference image, which may then be used to generate a more accurate 3D scene depth maps at the projector's current operating temperature.
