Abstract:
An optic system, comprising:a transceiving optic device having opposite first and second ends, and operative to collimate optical signals propagating therethrough and emitted via the first end and to focus optical signals propagating therethrough and emitted via the second end;a receiving optic device having opposite first and second ends, and operative to focus optical signals propagating therethrough and emitted via the second end thereof, wherein the first end of the receiving optic device is optically connected to the first end of the transceiving optic device such that the transceiving optic device is operative for transferring collimated optical energy to the receiving optic device; anda plurality of transmitting optic devices, each having opposite first and second ends and operative to collimate optical signals propagating therethrough and emitted via the first end thereof, wherein the first end of each of the transmitting optic devices is optically connected to the first end of the transceiving optic device such that the transceiving optic device is operative for receiving collimated optical energy from each of the transmitting of optic devices, andwherein the first end of at least one of the transmitting optic devices is substantially smaller than the first end of the receiving optic device such that substantially more optical energy is transferred from the transceiving optic device to the receiving optic device than from the transceiving optic device to at least one of the transmitting optic devices.
