In an evaluation device for determining a measurement value at a component, power is supplied to the component during readout of the measurement value. A controller serves to determine the power supplied to the component during the readout. The measurement value determined by the reader is corrected by a compensator while using the power determined by the controller, so as to obtain a corrected measurement value freed from any effects caused by the power supplied.

Concept for determining a measurement value at a component

A device for detecting electromagnetic radiation, with a diode structure acting absorbingly for the electromagnetic radiation and having a diode, and an ascertainer for ascertaining a measurement value for the absorbed electromagnetic radiation by means of at least two current/voltage measurements at the diode for different pairs of a diode current and a diode voltage.

Device and method for detecting electromagnetic radiation

For digitizing analog measurement signals, an analog-to-digital converter is used, wherein the offset to be subtracted from an analog measurement value is taken to account within a locked loop by means of which an analog-to-digital converter operating according to the modulation principle is fed back.

Apparatus and method for efficient analog-to-digital conversion

In a method for imaging, a plurality of image sensor elements is used, which generate different output signal values when using different exposure times. For each image sensor element, an image signal value is generated by generating a first output signal value when using a first exposure time and an associated second output signal value using a second exposure time. If the first output signal value does not exceed a threshold value associated thereto, the image signal value is calculated using a first calculating rule on the basis of the first output signal value. If the first output signal value exceeds the threshold value, the image signal value is calculated using at least a second calculating rule on the basis of at least the second output signal value. By the calculating rules, the first and second output signal values are shifted relative to each other and adjusted such that no detectable discontinuity occurs between an image signal value still calculated according to the first calculating rule and an image signal value already calculated according to the second calculating rule.
