Abstract

Illumination of a scene with a time-sequence of spatial light patterns enables clients within the scene to navigate, receive broadcast wireless data, or make subsequent space-division multiple access connections to a high bandwidth wireless system. We have developed dedicated binary pattern sequences, for use with arrays of light-emitting diodes (LEDs), which are projected on the area of interest. The LED arrays can be in either active-matrix or matrix-addressable format. The properties of the different sequences are compared theoretically and experimentally, highlighting a trade-off between position update rate and resilience against pixel cross-talk and interference.
