Patent number: 11240607Abstract: An optical microphone assembly comprises a rigid substrate; an interferometric arrangement, a light source, at least one photo detector and an enclosure. The interferometric arrangement comprises a membrane and at least one optical element spaced from the membrane, wherein the at least one optical element comprises a surface of the substrate and/or is disposed on a surface of the substrate. The light source is arranged to provide light to the interferometric arrangement such that a first portion of the light propagates along a first optical path via the interferometric arrangement and a second portion of the light propagates along a second different optical path via the interferometric arrangement, thereby giving rise to an optical path difference between the first and second optical paths which depends on a distance between the membrane and the optical element.Type: GrantFiled: May 15, 2019Date of Patent: February 1, 2022Assignee: SINTEF TTO ASInventors: Hallvard Angelskår, Thor Bakke, Ib-Rune Johansen, Matthieu Lacolle, Jakob Vennerød, Andreas Vogl, Dag Wang
