ABSTRACT:
A method and apparatus for converting mechanical motion displacement to an electrical signal is disclosed. A translucent light scattering member is located between a light source and a light sensor capable of generating an electrical signal representative of the intensity of the light received by the light sensor. The translucent member is moved in a direction parallel to the light beam between the light source and the light sensor in response to a mechanical motion displacement in such a manner that the intensity of the light received by the light sensor is a function of the mechanical motion displacement.
