ABSTRACT The resolution capabilities of an experimental image‐transmission system intended for microfilm library application have been investigated. The modulation‐transfer‐function concept is used as a quantitative measure of component and overallsystem performance. The theory of MTF is discussed with emphasis on the analogy between the spatialand temporal‐frequency domains. Practical techniques for measuring the MTF's of electro‐optical components are developed and results obtained from measurements made on specific components are presented. Also included in the paper are the conclusions which have been reached on line‐scan requirements for a highresolution microfilm facsimile system.
