1. Detector, comprising
a substrate;
a first channel comprising
a first sensor applied to the substrate, and
a first evaluation unit connected to the first sensor via a first contact point; and a second channel comprising
a second sensor applied laterally adjacent to the first sensor on the substrate, and
a second evaluation unit connected to the second sensor via a second contact point,
wherein the first sensor and the second sensor have identical designs and are each configured to measure an identical physical quantity, and
wherein, in response to a stimulus affecting the first sensor and the second sensor, the first sensor is configured to produce a first measurement signal, and the second sensor is configured to produce a second measurement signal that is equal in magnitude but of opposite polarity to the first measurement signal.
