METHOD FOR OPTIMIZING AN INTENSITY OF A USEFUL LIGHT DISTRIBUTION

摘要

A method for optimizing an intensity of a useful light distribution includes: providing a light source for emitting a light beam in a z-direction, which defines an optical axis, with a first intensity distribution; providing a beam shaping optical unit and a beam focusing optical unit for generating a second intensity distribution to be used in a target plane, the target plane being inclined by an angle ALPHA relative to a focal plane determined by the beam focusing optical unit; determining a first intensity at a first point and a second intensity at a second point of the second intensity distribution to be used. The points P1 and P2 are arranged on different sides of the back focal plane; and displacing the beam shaping optical unit along the y-axis in such a way that the difference between the two intensities 11 and 12 lies within a predefinable limit.

1. A method for optimizing an intensity of a useful light distribution comprising:
providing a light source for emitting a light beam in a z-direction, which defines an optical axis, with a first intensity distribution; providing a beam shaping optical unit and a beam focusing optical unit, which are arranged substantially perpendicularly to the z-direction in an x-y plane spanned by an x-direction and a y-direction, for generating a second intensity distribution to be used in a target plane, the target plane being inclined by an angle ALPHA relative to a focal plane determined by the beam focusing optical unit; determining a first intensity at a first point and a second intensity at a second point of the second intensity distribution to be used, the first point and the second point being arranged on different sides of the back focal plane; and displacing the beam shaping optical unit along a y-axis such that a difference between the first and second intensity lies within a predefinable limit.
