TRANSMITTING DATA TO A ROLLING SHUTTER SENSOR ARRAY VIA A LIGHT EMITTER ARRAY |
摘要 |
An array of light emitters is arranged single-file along an emitting surface of a transmitting device and emits light in a z-direction normal to the emitting surface. The array of light emitters is aligned along a y-direction normal to the z-direction. A lens assembly is optically coupled to the array of light emitters. The lens assembly includes at least one cylindrical lens and at least one aspherical lens. The lens assembly emits the light in free-space along the z-direction and has a first focal length in the y-direction and a different, second focal length in an x-direction. An encoder is coupled to apply a data signal to the array of light emitters. The data signal causes 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. |
