Full textTwo theories are to be found at the origin of this memoir. A fragment of the retinex theory by e. H. Land and the abney law about the interaction of two major wavelengths at the level of the luminosity and the field of transmittance. We shall work here on the relationship source surface. The first part of the memoir deals with the setting of a device of classifications made by individuals subjects on the one hand and on the other the systematic measures with spectrophometer of each one of the six sources and of each receiving surface (seven altogether, placed on a magnetic support which can be manipulated by each one of the forty subjects individuals). The setting up of this experimental device has taken about one year: and in the end, a method has been chosen for the reactions of the subjects as well as for the coherence of the results. One of the characteristics of the device deals with the mobility of the subject in front of the surfaces. In keeping with the answers obtained by the subjects a theoretical energetic classification has been set up from the measures of each sample and of each source on the spectrophotometer, integrating the efficiency luminancy coefficient in the photopic domain. The similitude of the results (93,27%) allows us to validate the abney law for the relationship between surface and support, as well as the classification method which has been used

Full textThe development of multi-wavelength and tunable sources could give the opportunity to facilitate the installation of fibre-optic wavelength-division-multiplexed systems of telecommunications and could also enable the reconfiguration of the network at the optical level. In that frame, the proposed work studies a ring fibre laser, which includes an erbium-doped fibre amplifier as gain medium and an electro-optically-tunable Lyot filter integrated on lithium niobate. When a continuous control is applied to the filter, we experimentally and numerically demonstrate that the wavelength of emission can be tuned over 18. 8 nm with power fluctuations not greater than 5. 7 dB. Furthermore, we observe that the switching of the laser wavelength is limited by the gain medium response. It is also shown that pulse generation can be achieved by use of an intracavity lithium niobate modulator and could be integrated as a new function on the filter chip. Finally, we investigate the behaviour of the laser when the filter transmission varies. When a "staircase" or saw-tooth signal is applied to the filter with a frequency lower than a few kilohertz, generation of sequences of pulses with different wavelength is demonstrated. At higher frequencies, sine-wave modulation of the filter transmission allows to create pulses via a new type of mode-locking technique

Full textHigh-Mass X-ray Binaries are interacting binary systems composed of a compact object orbiting an O/B massive star. These objects are deeply studied with the aim of understanding accretion and ejection processes around compact objects. Recent studies claim that most of the Galactic massive stars do not live alone and suffer from mass transfer during their life. Therefore, understanding the HMXB evolution and their interaction with the close environment allows to better understand not only the evolution of massive binary stars, possible progenitors of gamma-ray bursts and gravitational waves emitters during their coalescence, but also to correctly characterize the faraway galaxies. How do these sources evolve? Where are they located in the Galaxy? What are their principal properties? What is the influence of their environment? What is their impact on the interstellar medium? This thesis aims at shedding some light on these questions, by adopting two complementary approaches : a statistical study of the Galactic population of HMXB and on another hand a multi-wavelength study of individual sources
