- characterization of physical sensors and their conditioning circuits, metrological characteristics of the measurement chain
-Review of the characteristics of the sensors (linearity, sensitivity, resolution, etc.) and the associated electronic circuits.
- Environmental sensors (temperature, humidity)
- stress sensors and their reading circuits
- Micro-sensors and MEMS (MicroElectroMechanical System)
2°/ Acoustic sensors
- Elasticity and piezoelectricity of materials
- Sensors and static actuators: force, displacement, electrical voltage.
- Vibrating sensors. Resonance conditions. Equivalent electrical diagrams
- Signal processing in acoustics. Resonance. The time-frequency. Impedance matching. The electronics of generation and detection
- Transducers and imaging. Design and performance;. Ultrasound. Focusing in far and near fields ;. Acoustic imaging;
3°/ Thermal sensors
- Photometric measurements, infrared radiometric chain
- Figures of merit, CIP and detectivity of thermal detectors: bolometers, thermopile, pyroelectric sensor
4°/ Optical sensors for night vision imaging
- Optical infrared detectors and infrared imaging by thermal contrast (IR imaging).
- Visible optical detectors and residual light intensification imaging (IL imaging).
- Fusion Sensors
Laboratory: manufacturing in clean room and characterization of thermal micro-sensors and infrared photodiodes; Implementation of sensors within a measurement chain. Use of a latest generation thermal camera to perform thermography measurements in the industrial field.
