In terms of dynamic range and noise, optical sensors have great advantages over their electronic or mechanical counterparts. In addition, the noncontact nature of all optical measurements avoids influences of the sensor on the measured value and, thus, measurement-introduced systematic errors. This article gives an introduction to the components found in all kinds of optical sensors: light sources, detectors, and optical elements. On the basis of this optoelectronic toolbox, sensors for the measurement of various physical and chemical quantities are described.
