More Information
Summary:An optical transducer that uses a prism for the purpose of determining a load applied thereto which may be used to find the weight of an object. In accordance with known optical principals, when a load is applied to a material such as plastic, glass, crystal and the like, its index of refraction changes. By measuring the change of intensity of light internally reflected from a prism made of such material, the magnitude of a load applied thereto can be determined.
