Force imaging using frustrated total internal reflection

本课题的目的是开发一种简单的光学力传感器，通过受挫全内反射的原理。这种传感器将能够同时解析与波导接触的物体的局部接触力和局部牵引力。在有问题的力和测量的光学响应之间建立一个完整的理论框架也是令人感兴趣的。到目前为止，这一领域的工作表明，人们对这一概念有不同的兴趣，从用作模拟指纹识别方法的替代品，到通过跟踪穿着者鞋子上的局部压力和磨损位置来设计更有效的鞋子。

The purpose of this project is to develop a simple optical force sensor, through the principle of frustrated total internal reflection. This sensor would be capable of simultaneously resolving both local contact and local tractional forces of an object in contact with a waveguide. Developing a complete theoretical framework between the forces in question and the measured optical response is also of interest. Work in this area has thus far shown there are varying areas of interest in this concept, from use as a replacement for analogue fingerprinting methods, to designing more efficient footwear by tracking the local pressure and positions of wear on the wearer's shoe.
