Abstract
An optical transfer device for transferring optical signals from a moveable part to a stationary part through an optical transfer medium in order to minimize distortions of the optical signal and increase the effective bandwidth of the signal transit path by minimizing and/or maintaining equal alternate optical signal transit paths from the transmitter to the receiver.
Claims16
A device for transmitting optical signals between parts movable in relation to each other comprising:
- an optical transmitting unit having at least two transmitters for transmitting optical signals, said optical transmitting unit being movable along a path of movement;
- an optical receiving unit having a receiver for receiving the optical signals;
- and
- an optical transfer medium for optically coupling said optical transmitting unit to said optical receiving unit;
- wherein the length of said optical transfer medium is shorter than the path of movement along which said optical transmitting unit travels;
- and
- the at least two optical transmitters are spaced from each other along the path of movement of said transmitting unit such that optical signals from at least one of the optical transmitters is coupled into said optical transfer medium at any particular time.
A device for transmitting optical signals between parts movable in relation to each other comprising:
- a transmitting unit, movable along a direction of movement, and having a plurality of transmitters for transmitting optical signals;
- a receiving unit, having a plurality of receivers for receiving optical signals;
- a plurality of optical transfer mediums associated with said plurality of receivers;
- wherein the plurality of transmitters are greater in number than the plurality of receivers such that not every transmitter is coupled to every receiver at any particular time.
A device for transmitting optical signals between parts movable in relation to each other comprising:
- a movable unit, with an optical transmitting unit associated therewith for transmitting an optical signal;
- a stationary unit, with an optical receiving unit associated therewith for receiving the optical signal, the optical receiving unit having at least two receivers;
- an optical transfer medium associated with each of the at least two receivers, for conducting the optical signals to the at least two receivers respectively;
- wherein the transmitting unit is coupled to one of the at least two receivers at any particular time such that the optical signals are transmitted to fewer than all of the at least two receivers at any particular time.
