Abstract
The development of high speed data acquisition capabilities has made possible the recording of large volumes of data in short time spans. If this data is to be efficiently utilized, means for automatically reading, interpreting and analysing it must be developed. Modern high speed computers provide an effective data analysis tool. This paper presents a system which automatically reads, at high speeds, data recorded on photographic emulsion and which generates dynamic displays, an effective means for observing and demonstrating trends in data. The central component of the system is a UNIVAC 1105 computer which synchronizes and directs the operation of all peripheral components of the system. The film is read by positioning a spot of light on a C.R.T. at a computer specified point via two digital to analog converters, imaging this spot on the film, detecting the amount of light passed through the film with a photomultiplier and placing the binary equivalent of the detected value in the computer via an A-D converter. Dynamic displays are generated with a pulse operated 16mm motion picture camera which is viewing a C.R.T. The motion of the camera film and shutter are controlled by the computer as is the generation of the display points for each film frame.
