Abstract

The present invention provides a method for calibrating a detector device (2) under test, comprising a) emitting a number of n first laser pulses (P2-P4) by a first set (S1) of corresponding n laser sources (3a-d) of a plurality of laser sources (3a-d) in a first time slot (t1) and a number of m second laser pulses (P1) by a second set (S2) of m laser sources (3a-d) of the plurality of laser sources (3a-d) in a second time slot (t2) different from the first time slot (t1), wherein n ≥ 1, m ≥ 1, and n + m ≥ 3, wherein a ratio of n and m is defined as a predetermined pulse ratio n/m, wherein the first laser pulses (P2-P4) and the second laser pulses (P1) have a predetermined pulse energy; b) combining the first set (S1) of n laser pulses and the second set (S2) of m laser pulses to obtain a first combined laser pulse (PC1) in the first time slot (t1) and a second combined laser pulse (PC2) in the second time slot (t2); c) directing the first and second combined laser pulses (PC1, PC2) onto a detector (21) of the detector device (2); d) detecting the first combined laser pulse (PC1) in the first time slot (t1) and the second combined laser pulse (PC2) in the second time slot (t2) by the detector device (2) to provide corresponding first and second electric signals (61, 62); e) repeating steps a) to d) by regrouping the plurality of laser sources (3a-d) into a different first set (S1) of n laser sources (3a-d) and a different second set (S2) of m laser sources (3a-d) through all permutations (A-D) of the plurality of laser sources (3a-d) by keeping the predetermined pulse ratio n/m; and f) averaging each of the detected first and second electric signals (62) of all permutations (A-D) to obtain an averaged first electric signal (61') and an averaged second electric signal (62') indicative of the response of the detector device (2) for the predetermined pulse ratio n/m. Further, the present invention provides a corresponding calibration device for calibrating a detector device (2) under test.
