Abstract
A system comprising: an actuator; a signal generator configured to apply an electric signal to the actuator to expand and contract the actuator; an optical fibre associated with the actuator, the optical fibre configured to lengthen when the actuator expands and shorten when the actuator contracts; a coherent light source configured to transmit a coherent light through the optical fibre to provide illumination during the lengthening and shortening of the optical fibre.
Claims14
A system comprising:
- two or more actuators;
- a signal generator configured to apply an electric signal to each of the two or more actuators to expand and contract each of the two or more actuators;
- an optical fibre configured to lengthen when at least one of the two or more actuators expands, and wherein the optical fibre is configured to shorten when at least one of the two or more actuators contracts;
- a coherent light source configured to transmit a coherent light through the optical fibre to provide illumination during the lengthening and shortening of the optical fibre, wherein the coherent light is despeckled by transmitting the coherent light during the lengthening and shortening of the optical fibre and wherein the illumination is delivered to an optical storage medium.
1 more element
A method comprising:
- applying an electric signal to two or more actuators to expand and contract the two or more actuators;
- lengthening and shortening an optical fibre associated with at least one of the two or more actuators as the at least one of the two or more actuators expands and contracts;
- during the lengthening and shortening of the optical fibre, transmitting a coherent light through the optical fibre to provide illumination, wherein the coherent light is despeckled by transmitting the coherent light during the lengthening and shortening of the optical fibre and wherein the illumination is delivered to an optical storage medium.
