Abstract
The Apollo mission to the moon will be covered by television. This paper describes the lightweight, handheld TV camera that will be used by the Apollo astronauts. The camera's mission requirements, parameters, and system description are discussed. The special considerations in the selection of major designs, such as sensor, optics, power supply, and automatic light-level compensation are given. In addition, a detailed theory of operation of the video amplifier, yoke and deflection circuits, beam current regulator, and sync generator is presented. Since a prime requisite for the camera is light weight, hybrid and monolithic integrated circuits are used extensively in the camera electronics. A description of these circuits is given. Factors such as dynamic range of illumination, operation during a launch vibration environment, and handheld-sighting requirements with a narrow-angle zoom lens are discussed. The trade-offs between frame rate, resolution, and bandwidth relevant to image smear and image quality are also considered for this particular application.
