Fiber Optic Light Valve.
Abstract
A mechanically actuated, piezoelectrically powered, fiber optic connected light valve (shutter) utilized as a sensor to detect mechanical motion (pressure) or displacement. A piezoelectric element responds to pressure to generate an electrical signal which is applied to a Kerr cell containing nitrobenzene; the signal in turn renders the nitrobenzene transparent and light via fiber optic means is allowed to pass through the Kerr cell and return to the light source location for sensing.
