ABSTRACT:
The invention relates to a method of controlling several radiation-emitting elements. The invention consists in the compensation of differences in the emission power of the individual elements due to variations in the efficiency of the elements or to differing operating conditions by operating each radiation-emitting element with an individual pulse length determining the overall emission time. In this way, the energy emitted by all elements triggered is substantially identical.
