Title: Sigurd Lovseth: Innovator in Optical Interferometry

Introduction

Sigurd Lovseth is a notable inventor based in Trondheim, Norway. He has made significant contributions to the field of optical interferometry, particularly through his innovative patent that addresses coherence reduction in optical signals.

Latest Patents

Sigurd Lovseth holds a patent titled "Active coherence reduction for interferometer interrogation." This invention focuses on 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 then launched into an optical sensor network, which comprises multiple optical pathways leading to the detection unit. Pairs of these optical pathways form sensor interferometers. A compensating interferometer with a delay difference similar to the sensor delay difference may be arranged in a serially coupled manner with the optical sensor network, either before or after the network. The coherence modulation can be performed through direct modulation of the source or through external modulation of the light using various modulators.
