A simple device based on the principle of frustrated total internal reflection is used to image the regions of contact between rubber objects and a large-area perspex waveguide. Measurements of the intensity of light scattered at the interface are fo... Read More about Optical measurement of contact forces using frustrated total internal reflection.

Fingermarks are a key form of physical evidence for identifying persons of interest and linking them to the scene of a crime. Visualising latent (hidden) fingermarks can be difficult and the correct choice of techniques is essential to develop and pr...
