Ce livre, rédigé par des enseignants de Centrale Marseille, propose une approche unifiée des concepts qui fondent l'Optique physique, ce domaine clef de la Photonique qui va de l'Optique électromagnétique à l'Interférométrie en passant par la

International audience; In next generation space and ground-based instrumentation for Earth and Universe Observation, new instrument concepts include often non planar gratings. Their realization is complex and costly. We propose a new technology for

The measurement of very low reflection coefficients of anti-reflective coated interfaces has become a key issue for the realization of precision instruments such as the giant interferometers used for the detection of gravitational waves. We propose i

Capitalizing on a previous theoretical paper, we propose a novel approach, to our knowledge, that is different from the usual scattering measurements, one that is free of any mechanical movement or scanning. Scattering is measured along a single dire

We describe the latest improvements of our spectral and angular light scattering characterization apparatus (SALSA) and in particular its automatic spectral calibration using gas discharge sources.

We show how the use of a balanced low coherence interferometric scheme allows the ultra-low coefficient of reflection of a laser line antireflection coating to be ac-curately measured, together in amplitude and phase.

Following on from previous studies on motionless scatterometers based on the use of white light, we propose a new, to the best of our knowledge, experiment of white-light scattering that should overtake the previous ones in most situations. The setup
