1 st day:
- the sensors, the signals and the detection systems;
- the sensor classification;
- the unit of measurements;
- the transfer functions (mathematical models, calibration, computational of a stimulus);
- the sensor characteristics (span, accuracy, calibration error, nonlinearity, saturation, repeatability, resolution, uncertainty, output format, environmental factors).
2 nd day:
- the physical principles of sensing (electrical charges and fields, capacitance,
magnetism, induction, resistance, piezoelectric effect, hall effect, electro-optical effect,
thermoelectric effects, sound waves, temperature and thermal properties of materials,
heat transfer).
3r d day:
- the optical components of sensors (light, polarization, radiometry, photometry,
windows, prisms, mirrors, lenses, fiber optics and waveguides);
- the interface electronic circuits (signal conditioners, sensor connections, excitation
circuits, analog to digital converters, data transmission, noise in sensors and circuits,
batteries for low power sensors).
4 th day:
- case study: turbidity with a smatphone camera.
5th day:
- case study: digital holography and particle datection in water with a low cost real time test bench.
