Course detail

Technical Measurement

FSI-VTM Acad. year: 2024/2025 Winter semester

The subject is first focused on basic facts from the field of metrology. Since metrology is a very large field, only elementary and introductory information is given in this subject. For a broader understanding of the context, it is necessary to start from the recommended literature. Subsequently, students are introduced to the basic properties of measuring devices and preparations that are used in the measurement of the technical quantities described below. An overview of these quantities follows from the list of lectures. The teaching of this subject is supplemented by laboratory exercises on selected topics, their list is given in the overview of laboratory exercises.
