Abstract
Various light sources (illuminators), light transmitters, and recording apparatus are listed, and the shortcomings or inefficiencies of each group are analysed. A new, small and safe, high intensity illuminator is described together with possibilities of improved light transmission. The first results obtained using a small lightweight 35 mm full frame camera, with motorized film transport, as well as with a small 16 mm movie camera are mentioned. Finally, a miniature colour vidicon tv camera for endoscopic purposes is described.
