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). 描述了一种用于检测电磁辐射光谱的系统(100)，包括：传感器装置(20，1)，其包括"背靠背"配置的两个光电二极管，并被配置为将入射电磁辐射(EMR)转换为电流，作为依赖于电控制电压的相对光谱响应度的函数；电子控制和处理模块(50)，其被配置为：通过改变所述光谱响应度来选择性地向所述传感器装置(1)提供多个控制电压(VB)值，从而获得
