Abstract

A non-contacting optical system is described which can measure not only absolute displacements like comparable, more traditional transducers but also relative displacements. It can be cheap and, even under normal lighting conditions, operated non-intrusively at some distance from a test object which need not be reflective. Several examples are presented to illustrate the system's versatility in applications involving frequencies below 100 Hz
