Abstract

An optical tag (14), having a photo-detector (401), a controller (405), a piezoelectric translater (407), a battery (412) and a retro- reflective tape (409). The photo-detector is responsive to optical energy at a predetermined wavelength, and the controller is connected to the output of the photo-detector. The piezoelectric translator is connected to the controller and also to the battery when the photo- detector responds to the optical energy. The retro-reflective tape is directly mounted on the piezoelectric translator. When the connection between the piezoelectric translator and the battery is established, a pulse is generated and applied to the retro-reflective tape. Therefore, the optical energy incident on the retro-reflective tape is modulated by the pulse and retro-reflected by the retro- reflective tape.
