Abstract

The use of the evanescent wave coupling between a critically cut optical fibre and a glass plate is described. An experimentally demonstrated configuration is used to illustrate the principle in an analogue force/pressure sensor addressed by light from a He-Ne laser, and application to a non-intensity dependent measurement scheme is shown.
