Full textThe solar corona is the part of the Sun's atmosphere that extends from the photosphere (solar surface where the photons are emitted) into the interplanetary medium. Its understanding is a major issue because it is the source of phenomena that can disrupt telecommunications, living beings and even climate. The most appropriate tool to observe it is the coronagraph, an optical system obscuring the solar disk in favor of the corona, a million times fainter. My thesis deals with its review, particularly through the spaceprojects :- Solar Orbiter, which will approach the Sun at 0.2 astronomical unit (distance between Earth and Sun), allowing a very high spatial resolution ;- SMESE, in cooperation with China, which should study the corona in the Lymanalpha (and far infrared) ;- and ASPIICS, which will observe the corona in conditions close to a natural solar eclipse, with its occulting disk located at 150 m from the imaging instrument.The first point tackled is the rejection of instrumental stray light, whose optimization is one of the major problems in coronagraphy. The second concerns the methods of observation and imaging in white light, monochromatic imaging, and interferometry, in particular the Fabry Perot. The development and improvement of these techniques will allow considerable progress in terms of resolution and access to the corona ever closer to the Sun's surface, the location yet little known where the solar activity originates

Full textOver the last two decades, a large number of exoplanets have been confirmed with the rate of discovery increasing in recent years primarily as new instruments with improved sensitivities have become available. Direct imaging of an Earth-like planet is now an important goal of the science community. This is a challenging problem for two primary reasons. First, the intensity ratio between the bright star and its dim Earth-like companion is expected to be approximately ten orders of magnitude and, second, the angular separation to the star is very small.
An external occulter is a specially-shaped spacecraft that is flown in formation with a telescope in order to block most of the starlight before it reaches the entrance pupil thereby allowing planetary light outside of the occulter's inner working angle to become visible. Designing a shape for the occulter spacecraft to enable suppression over a wavelength band of interest requires modeling through scalar diffraction theory. Typical designs feature occulters that are tens of meters across at a separation of tens of thousands of kilometers from the space telescope.
In this dissertation, we focus on occulter design and scaling to enable experimental optical verification of occulters in the laboratory. We provide experimental results that establish a 10-5 suppression level in the pupil and 10-10 contrast in the focal plane, which are both approximately two orders of magnitude below the ideal performance of the testbed. We use numerical simulation to study the sensitivity of the occulter design in the laboratory and determine that performance is feature-size limited. We provide the design of a longer and flight-like occulter experiment, and study its sensitivity to determine the expected performance.

Full textOccult Hepatitis B infection (HBV), defined by HBV DNA positivity in absence of HBsAg in the serum was found in 30% of hepatitis of unknown aetiology and frequently among HCV chronic carriers. In order to better understand how HBV escape to diagnosis tests and determine the consequences of this co-infection on HCV chronic infection, we analyzed by ultra sensitive molecular tests developed in the lab, serum samples from 203 HCV chronic carriers before any antiviral treatment. The results from this first study showed that occult HBV infection frequency could reach 20% in France and that occult HBV infection may worsen the course of HCV infection being associated to a bad response to antiviral therapy and aggravation of liver disease. In order to perform the molecular characterization of hepatitis B viruses in cases of occult HBV infections, the whole HBV genome was amplified by a new technique developed in the lab, named Rolling Cycle Amplification (RCA), cloned and sequenced in a HCV transplanted case. The analysis of the cloned sequences did not show the presence of any of the known mutations in the viral genome that may explain HBsAg negativity. Our results suggest, on one hand, the implication of other factors in the suppression of the HBV replication and altered expression of HBV, on the other hand, the importance of extra hepatic sites of HBV replication during occult HBV infections, since it was able to persist after liver transplantation. Our work emphasise the need to develop new diagnostic and therapeutic tools in the case of occult HBV infections especially during co-infection with HCV
