ABSTRACT:
A system that provides temperature compensation in an optical transducer that uses a prism for the purpose of determining a load applied thereto and which may be used to find the weight of an object. When material such as plastic, glass, crystal and the like experiences a change in temperature, its index of refraction changes. By combining prisms, compensation may be made for the change of temperature.
