Abstract

The aim of Optical Digital Holography, applied to cells and tissue imaging, is to provide an accurate 3D imaging of biologic materials, down to the microscopic scale. The method has been developed to yield a very precise determination of cells and tissues morphology. Targeted accuracies are in the sub-micron range and allow for the observation of very small movements band deformations, produced, in particular, by depolarization of excitable cells and their metabolic activities. Direct imaging of tissue structures by the newly developed digital holography is deemed to offer unique investigation means in biology and medicine and attractive diagnostic capabilities.

Medical imaging

Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities.

Holography

Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating real , but it also has a wide range of other applications. In principle, it is possible to make a hologram for any type of wave. A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium.

Microscopy

Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye). There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy, along with the emerging field of X-ray microscopy. Optical microscopy and electron microscopy involve the diffraction, reflection, or refraction of electromagnetic radiation/electron beams interacting with the specimen, and the collection of the scattered radiation or another signal in order to create an image.
