Abstract
In accordance with an aspect of the invention, a system has a transmitter and a receiver, where the transmitter includes a beam source and an optical element. The beam source produces a beam that represents information, and the optical element alters the beam so that the beam has a uniform intensity over a cross-sectional area. The receiver is separated from the transmitter by free space through which the beam propagates and includes an active area positioned to receive a portion of the beam that the receiver converts into a received signal. To accommodate possible misalignment, the cross-sectional area of the beam is larger than the active area by an amount that accommodates a range of misalignment of the receiver with the transmitter.
