Title: Kjell Blotekjaer: Innovator in Optical Technologies
Introduction
Kjell Blotekjaer is a notable inventor based in Trondheim, Norway. He has made significant contributions to the field of optical technologies, holding a total of 3 patents. His work focuses on enhancing the performance and efficiency of optical systems, particularly in sensor applications.
Latest Patents
One of his latest patents is titled "Active coherence reduction for interferometer interrogation." This invention involves methods and apparatus that reduce the coherence of an optical signal used to interrogate optical interferometric sensors. The optical field phasor of the interrogation source is modulated in a controlled manner to produce a broadened optical source power spectrum at the output of the source unit. The output from the source unit is launched into an optical sensor network, which comprises multiple optical pathways leading to the detection unit. Pairs of optical pathways form sensor interferometers, and a compensating interferometer may be arranged in a serially coupled manner with the optical sensor network. This innovation allows for improved performance in optical sensing applications.
Another significant patent is the "Optical fiber coupler." This invention comprises a multimode fiber bus, an input branch fiber, and an output branch fiber. Coupling between the fibers is achieved through a reflector located in the core of the multimode optical fiber. The reflector is designed to reflect a small fraction of the light propagating in the multimode fiber towards the output branch fiber. This technology is particularly advantageous for local area networks and distributed sensor systems, enhancing the efficiency of optical communications.
