Measurement device for measuring light, measurement system and measurement method for detecting light parameters

A measurement system for detecting light parameters of light from a light source comprising

• a measurement device, which comprises an optical device configured to split a polarized light beam of the light into a first partial beam and a second partial beam, which have a defined phase shift relative to one another, a sensor device having at least two detector elements, which each have a polarization with a different orientation about an optical axis, and a channeling device configured to at least channel or discretize the light depending on a received light from the light source, the channeling device being optically connected upstream of the optical device, wherein the first and second partial beams are alignable to one another by the optical device to the detector elements to detect interference of the first and second partial beams by the detector elements,
• wherein the channeling device is configured to convert the received light into a single-channel light,
• wherein an evaluation device of the measurement system is configured to evaluate the interference to detect light parameters of the light,
• wherein the channeling device has a channeling element in the form of exactly one optical fiber for channeling the light.
