Abstract
The present application is directed a short distance free space optical communication link system. The system includes optical transmitter, receiver, beam expander, Rx lens and auxiliary alignment system.
Claims20
A system, comprising:
- a transmitter assembly including:
- an optical transmitter to send data and position data using a laser beam;
- a beamer coupled to the optical transmitter to shape the laser beam and transmit the laser beam;
- a receiver assembly including:
- a lens to focus the laser beam;
- and
- an optical receiver coupled to the lens to receive data, wherein the receiver assembly is moveable to optimize the reception of the laser beam.
4 more elements
A method to communicate with optical signals, comprising:
- sending data at an optical transmitter;
- applying a beam expander to make a diverged transmitted beam to enhance the power received by the receiver and Reduce receiver alignment tolerance;
- focusing the beam with a lens;
- and
- receiving the data with an optical receiver.
2 more elements
A system, comprising:
- a beamer to transmit optical data over air;
- a transmitter coupled to the beamer;
- a tracking light source coupled to the beamer;
- an optical receiver with a lens;
- and
- a motor to rotate the optical receiver;
- wherein the beamer optically communicates with a receiver unit including a receiving lens, with the motor moving the optical receiver in a two-dimensional rotating axis, the lens focusing a received tracking light to a position detector, wherein the received communication signal is directed to a photo-detector.
