Calibration of the Surveyor Television System

The data relayed by the Surveyor TV system has been improved by data-processing techniques. To effect this improvement the system must be calibrated by determination of the transfer function from the object space viewed by the camera to the data output of the ground support equipment. This includes the Surveyor TV camera system, the modulator and transmitter and the TV Ground Data-Handling System. The major parameters calibrated are light-transfer characteristics for black-and-white and color photography, shading characteristics, erasure characteristics, modulation transfer function, geometric linearity and accuracy of functional control. The calibration effort consists of (1) the collection of component, subassembly and system data during manufacturing and acceptance testing; (2) video recording of the calibration of the spacecraft TV system at Cape Kennedy prior to launch and (3) playback of the video calibration tapes through the ground support equipment.
