Abstract
A method of aligning an optical beam includes transmitting a first beam from a first optical transceiver to a second optical transceiver. A position of the second optical transceiver is adjusted based upon the received first beam. A second beam is transmitted from the second optical transceiver to the first optical transceiver. A command signal is transmitted from the second optical transceiver to the first optical transceiver. In response to the command signal, a position of the first optical transceiver is adjusted based upon the received second beam.
Claims20
A method of aligning an optical beam, comprising the steps of:
- transmitting a first beam from a first optical transceiver to a second optical transceiver;
- adjusting a position of the second optical transceiver based upon the received first beam;
- transmitting a second beam from the second optical transceiver to the first optical transceiver;
- transmitting a command signal from the second optical transceiver to the first optical transceiver;
- and
- in response to the command signal, adjusting a position of the first optical transceiver based upon the received second beam.
A method of providing an aligned optical beam, comprising the steps of:
- providing a first optical device including a first housing having a first optical transmitter and a first optical receiver;
- providing a second optical device including a second housing having a second optical transmitter and a second optical receiver;
- placing the first and second optical devices on opposite sides of a space to be monitored;
- orienting the first and second housings such that the first transmitter is aimed at the second receiver, and such that the second transmitter is aimed at the first receiver;
- transmitting a first beam from the first transmitter to the second receiver;
- adjusting a position of the second receiver to optimize a quality of the received first beam;
- transmitting a second beam from the second transmitter to the first receiver;
- transmitting a command signal from the second transmitter to the first receiver;
- and
- in response to the command signal, adjusting a position of the first receiver to optimize a quality of the received second beam.
A method of providing an aligned optical beam, said method comprising the steps of:
- providing a first optical device including a first optical transmitter and a first optical receiver;
- providing a second optical device including a second optical transmitter and a second optical receiver;
- placing the first and second optical devices on opposite sides of a space to be monitored;
- manually orienting the first and second optical devices such that the first transmitter is aimed in a general direction of the second receiver, and such that the second transmitter is aimed in a general direction of the first receiver;
- transmitting a first signal from the first transmitter to the second receiver;
- adjusting the first transmitter or the second receiver to maximize a signal strength of the received first signal;
- transmitting a second signal from the second transmitter to the first receiver;
- manually activating a control device on the first optical device or the second optical device;
- in response to the manual activation of the control device, transmitting a command signal from the first transmitter or the second transmitter;
- and
- in response to the command signal, adjusting the first receiver or the second transmitter to maximize a signal strength of the received second signal.
