ABSTRACT:
An optical data encoding and readout system for identifying an object and providing sensor data related to the condition of the object includes a liquid crystal cell for receiving a polarized readout beam. A control circuit reads identification and sensor data codes stored in a predetermined format in memory, and modulates the liquid crystal cell in accordance with the codes which in turn modulates the polarization of the readout beam.
