Remote control & power from optical energy transmitted down an optical fibre |
摘要 |
A remote device such as a control valve (4) is powered and controlled by optical energy, supplied by an intensity-modulated light source (8) and optical fibre (10). After conversion into electrical form, the light is detected at (12) and applied to a piezoelectric transformer (14). The output of the transformer powers and control an actuator (16) of the control valve.
