  • Passive optical transponder
    Patent number: 4049969
    Abstract: An optical identification and communication system wherein an interrogator sends out a broad illuminator beam outside the visible range. Some of this radiation is collected by the transponder optic and focused on a converting phosphor. The response light is recollimated by the transponder optic and transmitted directly back at the interrogator. The use of co-axial optics along with color filters and an electronic "shutter" in the interrogator enables the transmitted and received radiation to be separated.
