This book provides the basic concepts and fundamental principles of dynamic systems including experimental methods, calibration, signal conditioning, data acquisition and processing as well as the results presentation. How to select suitable sensors to measure is also introduced. It is an essential reference to students, lecturers, professionals and any interested lay readers in measurement technology.
- Introducing classical methods for signal conditioning, data acquisition, data processing and associated transmission, storage and display systems.
- Explaining the working principles of commonly used sensors and their typical applications.
Modern measurement technologies have a lot to offer in the measurement of mechanics, optics, acoustics, thermal and physical chemistry. Electromagnetic measurement, radio measurement, frequency measurement and radiation measurement can be realized. For different measurement scales, the measurements are used in a completely different way. Measurement technologies can be used to measure the mechanical stress on the surface of the part, the vibration of the machine and the random nature of the machining accuracy (correlation function, power spectrum). In recent years, with the development of computers, digital measurement technology has emerged, which converts analog quantities into digital quantities, and it is very easy to transfer measurement data into computers through the form of field buses. A number of new measuring devices with high integration, intelligence, information and modernization have been developed. These devices or technologies include fiber-optic grating measuring device based on optical fiber material, low-light image measuring device that breaks the application of human visual limit, intelligent measuring device that can take full advantage of big data, femtosecond laser detection technology based on femtosecond technology, quantum measurement technology widely used in medical and health fields, and seismic transverse wave measurement technology applied in geological exploration, petroleum and coal field exploration.
