Abstract

The present invention provides a method for calibrating a detector device under test, DUT, (2) with respect to linearity, comprising a) irradiating (M1) the DUT (2) with a first optical beam (31) and a second optical beam (41) for a predetermined time period, wherein the first optical beam (31) has a predetermined constant first optical power (32), and wherein the second optical beam (41) is an amplitude modulated optical beam, b) obtaining (M2) a detection signal (21) from the DUT (2), c) repeating (M3) steps a) and b) for a plurality of different predetermined first optical powers (32), d) calculating (M4) a derivative nonlinearity curve of the DUT (2) based on the obtained detection signals of the plurality of first optical powers (32), and e) providing (M5) a calibration curve to transform measured digital values into a linearized scale of optical power on the DUT (2) based on the calculated derivate transfer function (f') of the DUT (2). Further, the present invention provides a corresponding calibration device for calibrating a detector device (2) under test and an optical payload (102) for a satellite or an aircraft.
