Abstract: A device includes at least one array of photoconductors, at least one bias voltage source, and at least one photoconductor readout circuit. Each photoconductor is configured for exhibiting an electrical resistance dependent on an illumination of its light-sensitive region, and at least one photoconductor of the array is designed as characterizing photoconductor. The bias voltage source is configured for applying at least one alternating bias voltage to the characterizing photoconductor or at least one direct current (DC) bias voltage to the characterizing photoconductor. The photoconductor readout circuit is configured for determining of a response voltage of the characterizing photoconductor generated in response to the bias voltage. The response voltage is proportional to a variable characterizing the array of photoconductors. The photoconductor readout circuit configured for determining of the response voltage of the characterizing photoconductor during operation of the array of photoconductors.

Abstract: Disclosed herein are a detector array, a spectrometer system including the detector array and a method of using of the spectrometer system. The detector array includes a substrate; and a plurality of detector pixels applied to a surface of the substrate, where each detector pixel has a sensor region which is designated for receiving a partition of incident light, where each detector pixel is designated for generating a sensor signal depending on an intensity of the partition of the incident light received by the sensor region of the detector pixel, where at least two adjacent detector pixels share a single connection to a common electric potential, and where the sensor regions of at least two of the detector pixels differ with respect to each other by an area of the corresponding sensor region.
