“…Early efforts have focused on select use cases (e.g., smallscale photography, microscopy) where illumination-specific modifications are not required and standard integral imaging hardware can be directly repurposed as lighting equipment. In our past work [35]- [37], we have introduced the term integral illumination and explored the topic in more detail, identifying its unique constraints and technical challenges. To our knowledge, this paper stands as the first work to give a comprehensive overview of integral illumination, and present a viable design of a general-purpose integral illumination device backed by a functioning implementation.…”

Integral imaging, i.e., the use of lenticular optics to display stereoscopic/multiscopic images, is now being used in an array of products including glasses-free 3D displays. This paper describes integral illumination, an adaptation of integral imaging where fine-grained control of plenoptic light fields is used to realize new forms of programmable lighting. Relying on a combination of an imaging apparatus and custom lenticular optics, integral illumination devices can produce high-fidelity illusions of real and imagined light sources (e.g., spotlight, chandelier), replicating their illumination effects. Such devices have potential uses as ambient lighting fixtures, photography/videography equipment, components of artistic installations, etc. The paper will provide a general overview of integral illumination, describing its basic principles, hardware configuration, control mechanism, range of capabilities, and theoretical/practical limitations. We will also present a sample implementation of a working integral illumination device, describe its engineering details, report performance measurements, and discuss possibilities for future improvements and extensions.INDEX TERMS Integral illumination, integral imaging, plenoptic light field, programmable lighting.
