A device (100) for converting an acoustic signal (102) into an electric signal (104), wherein the device (100) includes an interferometer (106) including two mirrors (108) adapted for reflecting electromagnetic radiation (112) coupled into a space (110) between the mirrors (108). The acoustic signal (102) is to be coupled into the space (110) for influencing the electromagnetic radiation (112) in accordance with this acoustic signal. An electromagnetic radiation detector (112) is adapted for detecting the influenced electromagnetic radiation (112) and for converting the detected influenced electromagnetic radiation (112) into the electric signal (104) being indicative for the acoustic signal (102). An operation point stabilization unit stabilizes an operation point of the device (100). |
