Résumé : Digital holographic detection (DHM) provides a quantitative access to the optical phase which has widened considerably the field of investigation, especially in biological and environmental applications. This chapter proposes automated detection methods exploiting the full interferometric information. It describes the experimental protocol with the optical setup and the micro-fluidic device. Before presenting the detection methods, the chapter describes specific tools linked to the numerical propagation that are indispensable to process the information correctly, avoid numerical effects and make easier the further processing. The automated three-dimensional (3D) detection methods based on propagation matrices are then developed with a local and a global approach. Advantages and limitations of the different approaches are discussed and illustrated using concrete applications. Object detection procedures are an essential step for any real application.
