Claim Text:
1. A system comprising: an array of light emitters arranged single-file along an emitting surface of a transmitting device and emitting light in a z-direction normal to the emitting surface, the array of light emitters aligned along a y-direction normal to the z-direction; a lens assembly optically coupled to the array of light emitters, the lens assembly comprising at least one cylindrical lens and at least one aspherical lens, the lens assembly emitting the light in free-space along the z-direction and having a first focal length in the y-direction and a different, second focal length in an x-direction resulting in a relatively smaller y-direction field of view and a relatively larger x-direction field of view; and an encoder coupled to apply a data signal to the array of light emitters, the data signal causing the array of light emitters to illuminate in a pattern that switches at a rate corresponding to a rolling shutter of a receiving sensor array.
