Development of the opto-fluidic servo valve
Proceedings of the JFPS International Symposium on Fluid Power, 2002 An opto-pneumatic servo system employing opto-fluidic converter and pneumatic valve can operate the mechanical system directed by optical signal and work in hazardous environments because it does not use the electric immediate signal. The converter transforms the optical signal intensity into proportional fluid power, i.e.
