An Ethernet boat-to-shore lasercom link was established using a cat's eye modulating retro-reflector. High-definition video and data were transferred bi-directionally at ranges of 2 – 7.7 km.
<para> Modulating retro-reflector (MRR) systems typically use large area surface-normal modulators with large lateral current flow. Frequency response is limited by the resistance capacitance time constant. In cat's eye MRRs, only a small percentage of the modulator area is illuminated at a time. Uniform resistance to each part of the modulator is desired to decrease location dependence of frequency...
