Abstract : This report consists of two volumes. Volume I covers a discussion on the theory of image formation, and an application is made to television imaging systems. Volume II covers the results of the image evaluation experiment conducted as a part of ONR Contract Nonr364800. The purpose of this report is to provide objective methods of assessing characteristics of optical systems as opposed to the usual subjective approach. The objective characteristics considered were transfer characteristic, the sine wave response, and the signal-to-deviation ratio. However, in the final analysis, any valid objective estimate of image quality will have to pass the test of correlation with subjective impressions in future experiments. As a result of the image evaluation experiment and associated studies conducted under this contract, methods are now available to assess the characteristics of imaging systems prior to design. A common language is provided to describe the performance of elements in an optical system so that the complete system can be designed from the characteristics of the constituent elements. In order to effectively use the techniques developed, the requirements and the environment in which the system is to be used must be well defined. (Author)
