A “digital sundial” has recently been created using 3-D printing and open-source code [Ref: http://www.mojoptix.com/2015/10/25/mojoptix-001-digital-sundial/]. This high-tech product uses the classic strategy of using the shadow cast by sunlight to show the time; other sundials use a lens to focus sunlight onto a time-marker. This project will investigate the feasibility of using reflection of sunlight off the technical structures of diffraction gratings or holograms to create a passive solar-powered time-display device. It will involve theoretical work to investigate possible setups for a holographic sundial, and experimental work making and testing reflection holograms.
