The Law Enforcement Standards Laboratory of the National Bureau of Standards was established under the sponsorship of the National Institute of Law Enforcement and Criminal Justice of the Law Enforcement Assistance Agency of the Department of Justice. Its primary purpose is to develop standards, user guides and reports relating to equipment used in law enforcement and crime prevention. As a part of this program, the Optical Radiation section is developing standards for image intensifier night vision equipment. Since image quality is an essential criterion of the performance of any imaging system, a literature survey of image evaluation criteria and techniques was undertaken as a necessary preliminary step to the development of such standards. Because this information is not readily available in one reference, we are presenting it here.
