Abstract
Example embodiments may include a coaxial Free Space Optical (FSO) telescope providing a simplified and more precise structure. Example embodiment telescopes include a prism structure having at least two parallel surfaces associated with a filter and mirror. The filter may reflect or transmit optical signals based on their electromagnetic characteristics. Example embodiment systems include example embodiment coaxial FSO telescopes and transmitters and receivers for receiving and transmitting optical signals. A V-groove and/or lens array may be included in example embodiment FSO systems.

A coaxial free space optical (FSO) telescope comprising:
- a prism structure having at least first and second substantially parallel surfaces;
- a filter at the first parallel surface closer to a shared transit path of a plurality of optical signals transmitted or received by the FSO telescope, the filter configured to substantially pass a first optical signal of the plurality of optical signals to the second parallel surface and substantially reflect a second optical signal of the plurality of optical signals;
- and
- a mirror at the second parallel surface farther from the shared transit path, the mirror configured to reflect the first optical signal such that the first parallel surface transmits both the first and second optical signals on the shared transit path.
An FSO telescope system, comprising:
- an FSO telescope including,
- a prism structure having at least first and second substantially parallel surfaces,
- a filter at the first parallel surface closer to a shared transit path of a plurality of optical signals transmitted or received by the FSO telescope, the filter configured to substantially pass a first optical signal of the plurality of optical signals to the second parallel surface and substantially reflect a second optical signal of the plurality of optical signals, and
- a mirror at the second parallel surface farther from the shared transit path, the mirror configured to reflect the first optical signal such that the first parallel surface transmits both the first and second optical signals on the shared transit path;
- at least one transmitter configured to transmit at least one of the plurality of optical signals;
- and
- at least one receiver configured to receive at least one of the plurality of optical signals.
