Abstract [en]

Inductive microphones have been in use for a very long time and the progress of these have more or less stagnated. A “new” microphone is the laser-microphone. It is represented in the army as a so called direction microphone. The purpose of this paper is to show how a optical microphone could be developed. Components like semiconductor laser, photodetector and fibres have been used to build up an optical guitar-microphone. The advantage of using optical sensing is that it does not create any noise in the guitar-microphone and it will be feedback proof in relation to resonance in the guitar body and microphone casing.
