Objectives
Raise students' awareness of the many possible applications and wide variety of industrial sectors.
Teach them, through analysis of the physical principle, to quickly identify the advantages/disadvantages of the device and make an informed choice based on specifications and customer needs.
Microwave sensors section
Become familiar with the measurement of electric and magnetic fields in radio frequency and microwave applications in telecommunications and other industries, through the modeling and characterization of the most commonly used electric and magnetic field probes, and also through the use of standard microwave measurement instruments.
Description
This is an introduction to industrial applications of laser systems.
The course is based on an introduction to physical principles (time of flight, interferometry, triangulation, etc.), their respective advantages/disadvantages, and therefore a critical and comparative analysis of their limitations.
Examples of commercially available devices are presented, as well as numerous applications in sectors as varied as aeronautics and space, the environment, biomedicine, metallurgy and mechanics, automotive, etc.
Microwave sensors section
Electromagnetic probes: electromagnetic analysis of probes – electrical diagram models – characteristics of E and H probes – analysis of reference probes – probe design
Standard RF and microwave measurement instruments: Theoretical review of spectral analysis and dipole and quadrupole analysis in terms of S parameters – Block diagram of standard instruments and networks – Main characteristics of spectrum analyzers and networks – Choice of instruments according to applications
Applications: characterization of RF and microwave sources, components, and devices using probes, spectrum analyzers, and networks (examples: CW mode RF generator/preamplifiers/magnetic probes/electrical probes/directional couplers (waveguide version/planar version)/inductive coupling system, etc.)
Pre-requisites
