    Introduction

    The article starts with the following sentence.

    1. Overview and history

    2. Basics of holography

    Holography is a technique that enables a light field (which is generally the result of a light source scattered off objects) to be recorded and later reconstructed when the original light field is no longer present, due to the absence of the original objects.

    Reflection 1 - Holography

    The basic idea about a hologram is to create a 3D image of an object based on an interference pattern created by two lightsources.
    These lightsources are the images of the object stored as a reflection, the same as we see an object from 2 angles. What we see is a 3D object.
    It is important to remark that a hologram is not an object. It is an interplay of lightsignals.
