Abstract
A method for the adjustment of an optical measurement system comprises providing an optical measurement system, which comprises, as optical elements, a beam splitter; a first photo sensor, exposed by a first partial beam from the beam splitter; an optical filter; a second photo sensor, arranged downstream of the optical filter, exposed by a second partial beam from the beam splitter. Additionally, the angularity and relative position between multiple optical elements is designed to be adjustable. The method further comprises providing a device for generating a difference signal from the two photo sensors; providing a light source with periodically varying polarization; irradiating the light in the beam splitter, so that the two respective photo sensors are exposed by a partial beam; generating a difference signal of the output signals of the photo sensors; varying the position and/or angularity of at least one optical element, and observing the difference signal, determine the combination of angularity/position of the elements where a minimum difference signal is achieved, and configuring the angularity of the optical elements to the determined values. Further, a corresponding system is proposed.
