Abstract

We propose the study and the design of an ultra sensitive polarimetric torque sensor. The principle is based on the measurement of the torsion angle  induced on the shaft when a torque T is applied on it. This optical torque sensor has been tested for Aluminum, Steel and Plexiglas shafts with different geometries. The torsion angle has been measured with 0,001° accuracy. The torsion angle is then studied as a function of the applied torque. The comparison between the theoretical and the experimental results give us respectively 4.33%, 1.30% and 1.24% for the Plexiglas, the Aluminum and the Steel shafts. These results permit us good perspectives for our applications
