Light attenuation motion transducer wherein two fiber optic cables abut at the pivot axis of pivotable mounting members

摘要

A transducer is described which converts a mechanical motion input to variation in the light attenuation characteristic of a fiber optic cable by mounting the cable on and transverse of the pivot axis of mutually pivotable planar mounting surface members with the cable being severed at the mounting surface members pivot axis so as to effect a hinging action of abuttable cable severed ends with attendant light leakage in response to the mechanical motion input being coupled to at least one of the cable mounting surface members.
