Obiettivi dell'insegnamento

The aim of the course is to give a deep knowledge on modern optical and optoelectronic measurements: starting from the measurement of truly optical parameters of LASER light (spectrum, power, coherence, beam profile) and going into the applications of optical instrumentation and measurements in scientific and technological fields. The class will study measurement methods and electro-optical systems for material and devices characterization (e.g. optical spectroscopy and laser interferometry), for the optical communications, and instrumentation for industrial applications such as optical telemeters, interferometers, laser vibrometers and velocitmeters.


Risultati di apprendimento attesi

It is expected that the student will become able of understanding and solving problems related to optical instrumentation and measurements.

In particular, the ability of designing and using practical optical telemeters, interferometers, velocimeters and using optical laboratory instrumentation (optical power meter, optical spectrum analyzer, wavelength-meter) will be tested with written exercises and tests.


Argomenti trattati

 

Review of incoherent/coherent optical sources and lasers, photodetectors, noise in optical oscillators (amplitude and frequency). Laser telemetry: triangulators, Time-Of-Flight (pulsed/CW), LIDAR and DIAL. Measurements on optical sources: emission spectrum, spatial profile and beam divergence of LEDs and lasers. Power and energy measurements (optical power/energy meters). Polarization measurements. Optical Spectrum Analyzers (OSA). Monochromator and wavemeter for the measurement of optical wavelengths. Measurements for optical communications: Polarization Mode Dispersion (PMD); Optical Time Domain Reflectometry (OTDR); eye diagram and BER measurements on optical signal. Laser Doppler Velocimetry (LDV) and Particle Image Velocimetry (PIV), optical autovelox (tele-laser and laser-barrier). Laser interferometry. Industrial measurements: interferometric techniques for displacement and vibration measurements. Measurements of temperature, intrusion, vibration, using optical fibers.

 


Essay optional topics
Ultra-high-coherence interferometry for the detection of gravitational waves.
Stability and active stabilization of laser oscillators: natural and technical fluctuations of amplitude and frequency and their suppression using optoelectronic control loops.
Ultra-high-resolutions optical measurements: hi-res and Doppler-free laser spectroscopy; atoms manipulation (laser cooling and trapping of atoms); optical frequency clocks.

Modalità di valutazione

The exam consists of a written test with optional oral interrogation.
No partial examinations will be held during the semester.
The written test is made of 3-to-4 exercises, mostly with practical and numerical calculations, with the possibility of including some theoretical questions.
A large selection of previous classworks with solutions is available on the web page of the course.
The dates of the exams will be published well in advance in the class and on the web page of the course:
