Optical sensors
Research topics [Sensing & Cognition]
A variety of sensors use light or, more generally, electromagnetic waves to measure physical, chemical or biological parameters and properties. Recent examples are LIDAR and RADAR for determining the distance, geometry and speed of objects, which are currently developed for autonomous driving and gesture recognition, or spectrally selective sensors for determining the concentration and composition of substances via scattering and absorption of light. In the field of optogenetics, light is used to stimulate or inhibit nerve impulses: the development of the optical cochlear implant at TU Chemnitz aims to provide sound sensation to persons with hearing loss through activation of nerve cells in the inner ear by light. This topic is closely associated with visual sensing and optoelectronics.
The following scientific groups are working in the field of optical sensors:
