A number of recent developments in multiband cameras are discussed. In particular, descriptions are given of the 5065 camera used on Apollo 9, an optical multiplexing camera, the S190 camera for Skylab, and the return-beam-vidicon camera for the Earth Resources Technology Satellite. Also described are the use of an intensifier-vidicon storage tube system, a dispersing element and vidicon, an image dissector, and solid state arrays in four novel multiband cameras. The role of film and electro-optical multiband cameras in future space missions is discussed.
