Summary: | There is described a system (100) for detecting a spectrum of electromagnetic radiation, comprising: a sensor device (20, 1) comprising two photodiodes in a "back-to-back" configuration and configured to convert incident electromagnetic radiation (EMR) into a current as a function of a relative spectral responsivity dependent on an electrical control voltage; an electronic control and processing module (50) configured to: selectively provide a plurality of control voltage (VB) values to the sensor device (1) by varying the spectral responsivity, thereby obtaining a respective plurality of detection currents (Iph) associated with incident electromagnetic radiation; processing the value of the detection current (Iph) on the basis of the control voltage (VB) and the value of the spectral responsivity so as to obtain information (SP-ANS; iPST-IM).
