Abstract
An optical space transmission system includes a first optical collimator configured to transmit collimated light and change a directivity of transmitted collimated light, a second optical collimator configured to receive collimated light and change a directivity of received collimated light, and a reflector that is fixed and arranged on an optical path through which the first optical collimator and the second optical collimator are optically connected to each other.
Claims16
An optical space transmission system comprising:
- a first optical collimator configured to transmit collimated light and change a directivity of the collimated light as transmitted;
- a second optical collimator configured to receive the collimated light transmitted by the first optical collimator and change the directivity of the collimated light as received;
- and
- a reflector that is fixed and arranged on an optical path through which the first optical collimator and the second optical collimator are optically connected to each other,
- wherein
- the first optical collimator and the second optical collimator comprise optical collimating components configured to input and output the collimated light and mirrors whose tilt angle can be set to an angle at which the collimated light can be optically coupled to the optical collimating components,
- the reflector is arranged outside of the first optical collimator and the second optical collimator, and
- the mirrors are arranged inside of the first optical collimator and the second optical collimator.
An optical space transmission method comprising
- arranging a reflector fixed on an optical path through which a first optical collimator of which a directivity of transmitted collimated light can be changed is optically connected to a second optical collimator of which a directivity of received collimated light can be changed,
- arranging the reflector outside of the first optical collimator and the second optical collimator, and
- setting an angle of mirrors so that the collimated light can be optically coupled to optical collimating components that input and output the collimated light, the mirrors and the optical collimating components being arranged in the first optical collimator and the second optical collimator.
A tangible and non-transitory recording medium for a program of an optical space transmission system which causes a computer included in an optical space transmission system, the system including a reflector fixed on an optical path through which a first optical collimator of which a directivity of transmitted collimated light can be changed is optically connected to a second optical collimator of which a directivity of received collimated light can be changed, the program performing:
- a procedure for receiving a connection request from one of the first and second optical collimators to be optically coupled to each other, the connection request asking coupling to another optical collimator;
- a procedure for reading the directivities of the first and second optical collimators that are optically coupled to each other from a table in which the directivities of the first and second optical collimators optically coupled to each other are recorded;
- and
- a procedure for instructing the first optical collimator and the second optical collimator to set the directivities of the optical collimators to the directivities read from table.
