Device and method for measuring semiconductor-based light sources

A method for the sequential measurement of a plurality of optical pulses, comprising:

• emitting pulsed light radiation into an Ulbricht sphere via an inlet opening,
• measuring a first portion of the pulsed light radiation, which exits the Ulbricht sphere following interaction with the same through a first outlet opening, by means of at least one first detector and
• measuring a second portion of the pulsed light radiation, which exits the Ulbricht sphere without interaction with the same through a second outlet opening, by means of at least one second detector, which measures the temporal progression of the individual optical pulses, wherein the second detector comprises a photodiode, an A/D converter connected thereto and a digital memory, which records the temporal progression of the voltage and/or the current of the photodiode, and wherein the second detector detects the temporal progression with a temporal resolution of 10 ns or less.
