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, electric 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.
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.
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.
E-field sensor technology: The electric field is a quantity which can only be measured in a very tricky way since it can easily be disturbed. In this chapter, the main problems are discussed and the typical operating principles, both influence and electro-optical based ones, are described.
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.
Written exam at 29.06.2022:
At least 50% of the possible points are required in both sections (1. Sensorics, 2. Optoelectronic Devices). The material is defined by the lectures and the script.
Duration of the exam: maximum 90 min.
Those who cannot attend the written exam must make two oral appointments, one with G. Reider and one with F. Keplinger (franz.keplinger@tuwien.ac.at und georg.reider@tuwien.ac.at). The appointments are usually available on relatively short notice.
Coordinator of the course: Prof. F. Keplinger (franz.keplinger@tuwien.ac.at)
Help with organizational questions: M. Nuhsbaumer (martina.nuhsbaumer@tuwien.ac.at)
