Title: Kjetil Johannesen: Innovator in Optical Pressure Sensors

Introduction

Kjetil Johannesen is a notable inventor based in Trondheim, Norway. He has made significant contributions to the field of optical technology, particularly with his innovative designs in pressure sensing.

Latest Patents

Johannesen holds a patent for an optical pressure sensor. This invention features an optical fiber with a well-defined end part and a casing that has a cylindrically shaped cavity. The inner diameter of the casing is essentially the same as the outer diameter of the fiber. The optical fiber's end is positioned at a chosen axial position inside the cavity, effectively closing one end of it. A body within the cavity has a first, at least partially, reflective surface. The combination of the partially reflective surface, fiber, and casing defines a chamber that contains a compressible fluid. Notably, at least one of the body and the optical fiber is movably connected to the casing in the axial direction, providing a pressure coupling between the chamber and the environment. Johannesen's patent is a testament to his innovative approach to solving complex problems in pressure measurement.
