Abstract
A measuring apparatus and method which is sensitive to rotational but not translational or vibrational movement. The magnitude of an applied rotational force is determined based upon interference patterns created from light reflected from an interferometric prism positioned to rotate in response to an applied rotational force.
Claims10
A measuring apparatus sensitive to rotational but not translational or vibrational movement, said apparatus comprising:
- a bar suspended by a string;
- an interferometric prism attached to said bar;
- a light source directing a beam of coherent light at said prism;
- and
- a receiver receiving light reflected by said prism.

A method of measuring rotational movement without respect to translational or vibrational movement, the method comprising the steps of:
- suspending a bar by a string;
- attaching an interferometric prism to the bar;
- directing a beam of coherent light at the prism;
- and
- receiving light reflected by the prism.
