ABSTRACT:
A device for optical remote monitoring, preferably an optically readable membrane-based microphone, and a system including such a device is provided. The device for optical remote monitoring includes a retroreflector and an acoustic membrane. The acoustic membrane suitably is a light-modulating component and modulates the reflection of an incident light beam in relation to the pressure field, from a sound source, to which the membrane is exposed. The retroreflector may be a corner cube having three sides with the membrane arranged on one of the sides. The membrane can be part of a side or one side may consist of a membrane.
