This issue of Photonics Focus examines the science of illusion. Optical cloaking explores the advanced technology used to render objects invisible. A story on optical surface exposure dating explains how a light-based technique can be used to date ancient rock art. We also investigate the creation of deepfake images and the techniques being used to expose them. Finally, an issue on illusion would not be complete without a nod to Dennis Gabor, inventor of the hologram.
