Introduction to Holographic

Pierre-Alexandre Blanche, PhD

Abstract

This chapter presents an overview of the field of holography and is a prerequisite to the rest of the book. We are taking the approach of introducing holography by the viewpoint of diffraction optics. We will start by looking at the definition and properties of the simplest holograms: diffraction gratings. There is a lot to learn, and intuition to acquire, by understanding how these simple structures interact with light. We will then generalize the concept of diffraction to any pattern by introducing the scalar theory of diffraction. This theory allows to compute hologram for any image and location. Once these mathematic foundations are laid down, we will see the different experimental configurations to record, use, and take advantage of holograms.

A Short History

Welcome to the beautiful world of holography. With their shimmering color and ghostlike appearance, holograms have taken a hold in the popular imagination, and buzz marketing alike. This is a rare accomplishment for a scientific technique, that worth to be noted. Together with this general appreciation, comes the misinterpretation. The word “hologram” is sometimes associated to the phenomena that have nothing to do with the scientific usage of the term. It is not problematic in everyday life, but it can become conflicting when the technology penetrates the market. We have all heard about holographic glass, holographic how from deceased artists, holographic television, princess Leia hologram, etc. Some are holograms indeed, some are not. This book will help demystify holography, and I hope it will help you gain a new appreciation for the technique that can be applied in a lot of different circumstances.

There exist three possible ways to alter or change the trajectory of light: reflection, refraction, and diffraction. In our everyday experiences, we mostly encounter reflections from mirrors and flat surfaces, and refraction when we look through water, or wear prescription glasses. Scientists have used reflection and refraction for over 400 years to engineer powerful instruments such as telescopes and microscopes. Isaac Newton [1] championed the classical theory of light propagation as particles, which accurately described reflection and refraction. Diffraction, on the other hand, could not be explained by this corpuscular theory, and was only understood much later with the concept of wave propagation of light, first described by Huygens [2], and extensively developed later by Young [3] and Fresnel [4].
