Linda Law

Linda Law is a Digital / Holographic artist with a long history as an educator and writer about holograms. She has curated many shows of holographic art, developed educational programs about Holography for students of all ages in many forms, written for Advanced Imaging Magazine and Computer Graphics World in addition to working as a Fine Artist. These days she is the Executive Director of the HoloCenter and the Founding Director of The Virtual Museum of Holography. This new course on Ruzuku is an evolution of a live online course she has been teaching since the beginning of 2015.

What you will learn

This course will prepare you for the coming revolution in Digital Holograms. Optical Holograms have been with us for nearly 60 years, but it has taken until now for the technology to evolve to the point where digital holographic displays are practical. We are at the beginning of a new era of holographic imaging and this course is designed to educate you about what is already here and to prepare you for what is to come.

Course Instructor

The instructor for this course is Linda Law, a Holographic and Digital artist involved in the field of Holography since 1975 - in Holographic Research, Fine Art, curating exhibitions of Holograms, teaching classes and writing about this astonishing medium. Her early days in research at NY Institute of Technology (where she was the assistant director of the Center for Optics, Lasers and Holography) exposed her to the cutting edge of Computer Graphics Research at NYIT’s Computer Graphics Lab and began a journey towards working with what is now being manifested as Digital Holograms.  She is currently the Executive Director of the HoloCenter and the Founding Director of the Virtual Museum of Holography.

It has taken over 35 years for the technology to reach the point where computers are powerful and fast enough to handle the vast amounts of data processing and transfer that this requires. The internet has changed dramatically since those early days and now - finally - new displays have reached a high enough resolution and developments in Light Field Technology have made it possible to present dimensional, full color, moving images without goggles or glasses.

Course Content

This course will educate you on the history of Holography since the very beginning with Dr. Dennis Gabor in 1947 and it will ground you in the many types of holograms and the techniques required to make them. Before digital displays, holographic artworks needed to be seen in person.  Understanding the creative possibilities of Optical Holography will give you a foundation for creating content as we shift into digital holographic displays.

Digital Holography offers new tools for creating dimensional imagery but there is much to be learned from the amazing work that came first in the form of Optical Holograms. Artists around the world have been making Fine Art holograms using lasers since the late ’60s and a large body of creative holographic images are waiting to be revealed to an audience that barely knows they exist.

We will also take a deep look at what is not holography. There is much misinformation out there on the internet from companies that purport to have holograms but are really using old 2D technology (Pepper’s Ghost) dressed up with the latest digital projection techniques. In this course you will learn the disparity between these faux holograms and the real thing - there is a vast difference. Other techniques like lenticular images will also be explored to clearly show the transition from stereo imaging through a multi-view display technology that has laid the groundwork for Light Field Technology.

There is also much overlap with the latest developments in VR/AR/XR and many of the tools being used to create content for these immersive experiences are relevant for the latest digital holographic techniques. Volumetric imaging displays are also appearing and we will discuss the pros and cons of each of these new developments.

In the last couple of sessions, we will explore Light Field Technology, its origins, and the advances that have been made in recent years. Starting with the Plenoptic camera and its beginnings in the 1900s, we will look at the early stages of the commercialization of this technology by Lytro Inc. and the evolution of their light field camera. We will take a look at how we can create content for this new medium and explore the latest displays currently on the market including those most likely to be launched in the coming months and years.


We are at the beginning of a new journey. Imaging systems are being developed to capture dimensional content, the software is becoming available to edit spatial imagery and dimensional storylines, Holographic Displays are starting to become available, software is evolving to handle the data compression, standards are being written for data transfer and many artists and companies are experimenting with the process of content creation. 

Who should take this course

This course is appropriate for a range of students from artists, 3D animators, architects, filmmakers, producers, directors, designers as well as company executives who want to understand the latest dimensional images to present and advertise their products. This overview of the current dimensional imaging technologies will give you a solid foundation to begin to work from. It will help you to assess and make your own intelligent choices regarding the types of images and ways of presenting them that you want to employ for your company or that you might wish to work with creatively.
