Résumé

This thesis is dedicated to saturated speckle imaging, a novel technique which uses speckle patterns as a super-resolution imaging tool. This technique and the principal result obtained with it are deeply discussed in chapters 2 and 3, while chapter 1 contextualizes our work. In this chapter we present the primary ingredients of our study. Namely in section 1.1 we will introduce the concept of super-resolution optical microscopy. We will also discuss the application of super-resolution in complex media, such as biological tissues, where scattering is a major issue. Section 1.2 covers this topic and introduces some first considerations on speckle patterns. In section 1.3 we illustrate how imaging is possible exploiting the properties of speckle patterns and describe the imaging techniques that made use of such a random illumination. The motivations and outlines of this work are summarized in section 1.4.
