Force imaging using frustrated total internal reflection

本项目的目的是通过受阻全内反射原理，研制一种简单的光学力传感器。这种传感器将能够同时分辨与波导接触的物体的局部接触力和局部牵引力。在所讨论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很有意义的。到目前为止，这一领域的研究表明，这一概念有不同的兴趣领域，从用作模拟指纹方法的替代品，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.
