| 摘要 |
The present invention relates to an optical identification tag, a reader, and a system, and more particularly, to an optical identification tag which transmits its identification information using energy input in an optical form, and an optical identification system and reader using the optical identification tag. The present invention provides an optical identification tag and an optical identification reader. The optical identification tag includes a solar cell for converting incident light into an electrical energy, a circuit for providing a transmitted electrical signal corresponding to identification information, and a light emitter for providing a transmitted optical signal corresponding to the transmitted electrical signal, and the optical identification reader provides the incident light to the optical identification tag, and receives the transmitted optical signal from the optical identification tag.
