Basic Fundamentals of Digital Holography

Résumé

This chapter introduces the principles of digital holography, as well as the associated reconstruction methods. It presents the basic properties related to a digital hologram. In order to discuss the digital reconstruction of the object wave at the object plane, the chapter presents the basics of the scalar diffraction of light. Algorithms used to back-propagate the object field estimated at the sensor plane are based on this approach. The chapter discusses the use of the theoretical basics of wave propagation to numerically reconstruct the object wave at the object plane. It also discusses the different experimental configurations to record a digital hologram. The chapter provides basic experimental arrangements and gives few explications on how it works. Digital holographic interferometry exploits not only the amplitude of the object, but also its phase. Finally, the chapter describes the basic principle of digital holographic interferometry, and quantitative phase tomography.
