<p>The invention relates to optical devices, particularly to an optical displacement transducer for detecting a light flow received by a light sensor and subsequent determination of the amount of force applied to an object within which the optical displacement transducer is mounted. The transducer utilizes a light source which is mounted within a housing having a translucent face, and a light sensor mounted in a body having a corresponding translucent face. The light flow which travels between the translucent faces is intermittently blocked by a shadow rod moving between the light source and the light sensor in response to an external force applied to the shadow rod.</p> |
