Abstract:
An embodiment of the present invention includes a display device including a mechanical indicator, a reference photodetector, a measurement photodetector, and an opaque shroud. The opaque shroud is connected to the mechanical indicator to variably cover the measurement photodetector based on a position of the mechanical indicator. The opaque shroud does not cover the reference photodetector.
