Abstract :
We report an independently-addressed micro tunable cat´s eye retro-reflector array. The device aims at serving as the ID tag in an optical identification system, hopefully a superior alternative to the current RFID systems. Dynamic images have been successfully generated by the tunable cat´s eye array.
