Abstract
A system includes a plurality of photodiode sensors spaced from one another and mounted to a reflective surface, a transparent layer spaced from and substantially parallel to the reflective surface, and a plurality of photodiode transmitters at least one of mounted to the reflective surface and disposed between the reflective surface and the transparent layer.
Claims20
A system, comprising:
- a plurality of photodiode sensors spaced from one another and mounted to a reflective surface;
- a transparent layer spaced from and substantially parallel to the reflective surface;
- and
- a plurality of photodiode transmitters at least one of mounted to the reflective surface and disposed between the reflective surface and the transparent layer.

A system, comprising:
- a plurality of means for sensing light spaced from one another and mounted to a reflective surface;
- a transparent layer spaced from and substantially parallel to the reflective surface;
- and
- a plurality of means for transmitting light at least one of mounted to the reflective surface and disposed between the reflective surface and the transparent layer.
1 more element
A computer, comprising a processor and a memory, the memory storing instructions executable by the processor to:
- actuate a plurality of photodiode sensors spaced from one another and mounted to a reflective surface to sense received light;
- and
- actuate a plurality of photodiode transmitters, at least one of mounted to the reflective surface and disposed between the reflective surface and a transparent layer, to transmit light, wherein the transparent layer is spaced from and substantially parallel to the reflective surface.
