Computer-generated holograms have been a means of manipulating light for over 30 years; however it is recent developments in liquid crystal over silicon VLSI technology that has allowed them to become a commercial reality. In this presentation, I shall give an overview of how these holograms work. I shall then review activities at Cambridge in computer-generated holography over the last 10 years. This will include work on all-optical reconfigurable switches for telecommunications through to the recent commercial successes of holography for 2D and 3D projection display systems. I will also be looking into the future of this technology and the possible impact it may have on the fundamental concept of images, pixels and resolution.
