beam 14 in a first example configuration the configuration shows the angular direction of the beams with respect to the relative position of the transceiver telescope 1 which includes lenses 16 for the purpose of focusing incoming received beam 14 at the focal plane of the device the received beam 14 arrives from a remote transmitter or target not shown which preferably is identical to the preferred embodiment as illustrated herein but may be any other form of optical transmitter in alternative embodiments the received beam 14 arrives in an expanded form such that only a portion of received signal is actually captured by receiver telescope 1 and focused on the receiver focal plane at mirror 5 through receiver lens system 16 the received beam angle of arrival determines the location of the focused spot on mirror 5 at receiver focal plane on control assembly 3 as shown in this case the focused spot is below the center of the focal plane because the received beam 14 arrived at an angle inclined above the perpendicular line of sight of telescope 1 this position will be designated herein as y n and x m mirror 5 provides a return signal in the precisely opposite direction of incoming signal 14 regardless of where in mirror 5 the focused spot is presented a.
