Objectives
At the end of this course, students will have skills on:
1°/ Basic sensor characteristics :
- characterization of physical sensors and their conditioning circuits, metrological characteristics of the measurement chain
-review of sensor characteristics (linearity, sensitivity, resolution, etc.) and associated electronic circuits.
- Environmental sensors (temperature, humidity)
- stress sensors and their readout circuits
- Micro-sensors and MEMS (MicroElectroMechanical Systems)
2°/ Acoustic sensors
- Elasticity and piezoelectricity of materials
- Static sensors and actuators: force, displacement, electrical voltage.
- Vibrating sensors. Resonance conditions. Equivalent electrical diagrams
- Signal processing in acoustics. Resonance. Time-frequency. Impedance matching. Generation and detection electronics
- Transducers and imaging. Design and performance. Ultrasonics. Focusing in far and near fields ;. Acoustic imaging;
3°/ Thermal sensors
- Photometric measurements, infrared radiometric chain
- Figures of merit, CIP and detectivity of thermal sensors: bolometers, thermopile, pyroelectric sensor
4°/ Optical sensors for night vision imaging
- Optical infrared detectors and thermal contrast infrared imaging (IR imaging).
- Visible optical detectors and residual light intensification (IL) imaging.
- Fusion Sensors
Laboratory: cleanroom manufacture and characterization of thermal microsensors and infrared photodiodes; implementation of sensors within a measurement chain. Use of a state-of-the-art thermal imaging camera for industrial thermography measurements.
