Digital Holography Applications And Emerging Technologies

With the rapid growth of computing and display technologies, digital holography (DH) has undergone significant advancement in the past two decades. Contemporary research works have enabled holography, a technology which is originally intended for displaying three-dimensional (3-D) images, to be deployed in numerous scientific, engineering, and bio-medical applications. Notably, digital holography has been incorporated into quite a number of contemporary applications, such as, but limited to holographic cryptography, optical metrology, remote sensing and inspection, and more recently, quantum computing. The success attained with DH so far does not limit its development to its current state-of-the-art, but rather research on holography keeps on expanding, with new ideas and methods keep coming up in a sustainable manner. This Research Topic aims to collect representative works from experts in the field, with the aim of providing an insight on the overall picture on digital holography, as well as reporting existing methodologies and emerging technologies that are likely to have strong impact on future research directions. Participating in the Research Topic, either as authors or readers, also facilitates establishing a platform for researchers to network, and to share their knowledge.

What Is 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 three-dimensional images, but it also has a wide range of other applications. In principle, it is possible to make a hologram for any type of wave.
