Abstract
A system for eye tracking is disclosed. The system may detect illumination including a first wavelength emitted from one or more illumination sources. The illumination may propagate along a waveguide(s) to a termination node(s) associated with the waveguide(s). The system may detect the illumination propagating a remote fluorophore located at the termination node(s). The system may determine that the remote fluorophore shifted the first wavelength to a second wavelength such that the illumination includes the second wavelength.
Claims20
A device comprising:
- at least one camera;
- one or more illumination sources;
- and
- at least one processor and a non-transitory memory including computer-executable instructions, which when executed by the processor, cause the device to at least:
- detect illumination comprising a first wavelength emitted from the one or more illumination sources, wherein the illumination propagates along at least one waveguide to at least one termination node associated with the at least one waveguide;
- detect the illumination propagating a remote fluorophore located at the at least one termination node;
- and
- determine that the remote fluorophore shifted the first wavelength to a second wavelength such that the illumination comprises the second wavelength.
