An evaluation device for evaluating analog measuring signals of a detector, e.g., an IR detector, includes: an analog/digital converter device for digitally converting the analog measuring signal of the detector or an analog signal derived from the analog measuring signal into a digital measuring signal; a control device for receiving the digital measuring signal; and a subtraction device. The evaluation device receives a first analog measuring signal from a first measurement and stores the digital measuring signal formed from the first analog measuring signal, and also receives a second analog measuring signal from a second measurement. The subtraction device receives the analog measuring signal of the second measurement and an analog comparison signal formed as a function of the stored digital measuring signal of the first measurement, and forms a differential signal.
