Development of optical torque sensor
Development of optical torque sensor
The core of research is developing a small scale torque sensor with contactless measuring system.
The basic principle is upon the birefringence effect of optically active materials. Here a Perspex tube of thin wall thickness is used. When torque is applied, stress arising in the tube changes relative retardation, causing the change in light intensity which could be measured optically. The main goal of this study is to create a torque sensor of industrial application.
