Many biomedical measurement techniques are based on electric, magnetic and/or optical effects. Furthermore, in the human body several processes take place that find their origin in electric and optical phenomena, for example nerve conduction, electrical activation of the heart, and human sight.This course will concentrate on the physical background of electrical, magnetic and optical phenomena. Applications in the field of biomedical engineering will be given as examples. Lectures will be complemented by demonstrations, exercises and examinations.
The following topics will be treated: electrostatics, the electric field, electric potential, capacitors, current and resistance, the magnetic field. Within optics the following will be treated: geometrical optics, optical instruments (incl. the eye), interference, diffraction, polarization, microscopy.
