Abstract:
An optic system, comprising:a first optic device having opposite first and second ends, and operative to collimate a first optical signal propagating therethrough and emitted via the first end;a second optic device having opposite first and second ends, and operative to focus any optical signal propagating therethrough and emitted via the second end thereof, wherein the first end of the second optic device is optically connected to the first end of the first optic device such that the first optic device transmits the first optical signal in a first direction to the second optic device, with the first optical signal not being substantially reflected or refracted at any position between the first and second optic devices;a third optic device having opposite first and second ends, wherein the first end of the third optic device is optically connected to the first end of the second optic device such that the third optic device transmits a second optical signal substantially in the first direction to the second optic device, with the second optical signal not being substantially reflected or refracted at any position between the third and second optic devices; anda fourth optic device having opposite first and second ends, wherein the first end of the fourth optic device is optically connected to the first end of the first optic device such that the first optic device transmits the first optical signal substantially in the first direction to the fourth optic device, with the first optical signal not being substantially reflected or refracted at any position between the first and fourth optic devices,wherein the third and fourth optic devices are arranged and operative so that the fourth optic device does not receive the second optical signal transmitted from the third optic device.
