Technician producing interference gratings. Here, a laser beam is being divided and then recombined to generate a very fine pattern of interference fringes (parallel light and dark bands). These fringes are then recorded on a photosensitive material. These will then be used in subsequent experiments to alter the properties of light for analysis. Photographed at the National Physical Laboratory, Teddington, UK.
