Abstract
The invention relates to an optical pressure sensor based on light intensity measurements and comprises at least one membrane and two parallel optical fibers. At least one first fiber has a fiber end and a light emission surface for emitting light in the direction of the membrane. At least one second fiber has a fiber end having a light admission surface for receiving the light reflected from the membrane and transmitting that reflected light. The light emission surface and the light admission surface of the two fibers are disposed facing away from each other. This changes the optical path of the light during use such that the light portion received by the at least one second fiber is very sensitive to the position of the membrane.
