Basic Optics of a Television Film Chain

The fundamental optical principles involved in the projection of film into a television camera are reviewed. First, direct projection into a vidicon tube is cited. Then the relay system with its intermediate image is described in terms of the function of each optical element, the importance of proper alignment, and the mistakes to be avoided when a film chain is set up. Next, the requirements of multiplexing systems are discussed. Finally, three basic optical formulas are given by which approximate values can be obtained to aid in the design and coordination of equipment.
