Abstract

The proper collimating of the laser beam between the fiber optics transmitter and receiver is among the most important requirements to free space telecommunications. The targeting of the receiver over near-horizontal propagation in kilometers long distance requires fast control of the tip/tilt deviation of the laser beam emitting from the fiber optic transmitter because of beam direction fluctuations due to atmospheric turbulences. This deviation can be accomplished with fast deviation of the fiber optics emitting tip placed into focus of the collimating lens. Similar control could allow one to keep the input fiber optics tip in focus of the receiver's input lens. In this report we describe the design of the compact adaptive fiber optics collimator based on the X-Y positioner of the fiber optics tip utilizing the piezoelectric bimorph actuators for X-Y displacement of the fiber tip placed in the focal planes of the transceiver.
