- Abstract
- A three-vidicon live-color TV camera has been designed primarily for closed-circuit use, but it can be adapted for broadcasting. Its demagnifying relay system simplifies optical problems. The 35mm single-lens-reflex format was chosen for the objective lens to maximize lens availability and minimize cost. Plate beamsplitters employing dichroic coatings were computer designed to minimize hue shift and polarization and angle difference. The camera is completely self-contained and includes sync generator and encoder, requiring only 117-V ac power and a single coaxial output connection. Optical and mechanical alignment is factory set with precise jigs; the critical optical elements are sealed in a single removable subassembly. The stable sweep circuits require an absolute minimum of adjustment for achieving and maintaining registration. Other design features are: video circuits to provide stability of gain and dc level; a crystal-controlled syncgenerator; the camera adaptable to systems of any complexity; and remote control of all critical operating parameters. Sensitivity enables usable color pictures to be obtained with as little as 75-fc illumination.
