Objective

The course illustrates to the student the experimental basis of physics. It gives the student insight in how the physical laws and equations introduced in the engineering applications can be tested. It also gives to the student a versatile picture about both traditional measurement devices and modern computer-based measuring systems which, for example, make possible real-time observation and data collection of time-dependent quantities. Computer-based systems are used to measure very rapidly changing effects and using software analysing tools system properties can be calculated.


-----
When completing this course the student gets experience in making measurements: the student learns how to use variety of measuring devices and becomes aware of the possibilities of modern measuring systems. The student learns applications of computer-based measurement systems and sensors and achieves skills of estimating measurement uncertainties and writing reports. Student is learning modern computer-based graphical analysing tools in different measurement projects.

Content

Laboratory exercises and experiments are carried out by students working in small groups. Both traditional and computer-based measurement systems are used. Students are also taught mathematical methods for analyzing data. In many experiments computers are applied for data collection, analysis and graphical display of data. Basic concepts of error analysis and uncertainty estimation are introduced. Error estimation with statistical methods are introduced using computer software tools. Students write reports including descriptions of the experimental arrangements and observations, data analysis, final results and uncertainty estimates.
