    Abstract

    A solution for reading detector arrays is disclosed. The solution comprises generating (400) an excitation signal, varying (402) the frequency of the excitation signal in time, supplying (404) the excitation signal to a detector array comprising a set of thermal detectors. The number of detectors corresponds to the frequencies of the excitation signal. In the solution, the signal is demodulated (406) at the output of the detector array and time-multiplexed base band signal is obtained. An analogue to digital conversion is performed (408) to the time-multiplexed base band signal and the base band signal is demultiplexed (410) to obtain a set of detector signals.
