Research and Developments in Holography

Holography allows us to write different applications for people other than developers and engineers to understand user's needs. This technology can be an auxiliary to the fifth sense for differently able people. This technology will bring fundamental changes in the field of science and technology. No matter how much one is familiar with holography, a scientist or an ordinary person, he would soon engage with holography spontaneously. Increasing applications of holography will soon find their way through everyday life. But the technology still makes an impact today, although not with the same punch it had a quarter-century ago. Nowadays, holography has many growing applications in different sciences such as biology, medicine, IT, communication, architecture, security, and packing. There are optical applications existing for holography, and some of them are still developing. Making holographic three-dimensional displays providing realistic images without the need for special eyewear is one the most interesting application of holography. The 21 st century is said to be a photon century. People meet contemporary optics applications everywhere. It would be appropriate to increase the common education level in this field for people to be able to understand new surrounding technologies, entering our everyday lives. Optics serves as an important part of many scientific experimental methods. This way, such information could be useful also for researchers without a professional optical education. The most advantage of holographic 3D displays is the possibility to observe 3D images without using glasses. The quality of created images by this method has surprised everyone. This book is intended to covers the basic principles of holography and some current research and developments in the field. Advanced applications of holography including sensors, holographic gratings, and white-light viewable holographic stereograms are also covered.

The aim of this book is to study the recent improvements in creating three-dimensional images and videos by means of holographic techniques. Now, holography is a modern world technology created for the complete distribution of wave information. The future depends on the hologram. This allows us to maintain an inexpensive approach to the production of equipment. Nowadays, the most beautiful 3D pictures and movies are created by means of holograms. The book also discusses the potentials of holography to be applied in future. In this book, the experimental steps of making a transmission hologram have been mentioned, and current advances of this science-art will be discussed.
