After successful completion of the course, students are able to discuss the underlying problems in capturing the respective measurands in the complementary areas of sensor technology (acoustic sensors, ion sensors, megnet field sensors) and to analyze typical technical solutions.
In the field of optical sensor technology, students are able to understand, describe and perform simple calculations on interferometric sensors, the properties of optical detectors, the basics of imaging optics (ABCD formalism, Fourier optics) and physiological light measurement technology.
Optical Sensors: This part of the lecture deals with interferometric optical sensors (especially fiber gyroscope, Doppler velocimetry, integrated sensors), with the properties of optical detectors (image sensors, single-photon detectors), with the basics of imaging optics (ABCD formalism, Fourier optics) and physiological light measurement.
Acoustic sensors: Especially this sub-area of sensor technology is focused on the acquisition of sound signals, which are ultimately directly or indirectly related to human perception. Consequently, the lecture conveys first the function of the ear with the required fundamentals and dimensions of the acoustics. In the technical part the different microphone types up to the MEMS microphone in the mobile phones are treated.
Ion sensors: Sensors of this category are distinguished by a completely different principle, in particular by the formation of electrical voltages at interfaces. Again, the presented fundamentals help to gain a deeper understanding of the functionality and typical sensor problems. The chip with currently most sensors (10 ^ 9!) Can be found here and is used for DNA sequencing. This underlines the importance in the field of automation technology and computer science.
Magnetic field sensors: Magnetic field sensors have established themselves particularly in the field of data storage (hard disk) and for robust applications such as in the car (for example, speed measurement). This chapter deals with the main functional principles.
