title: Effects of target contrast and background upon tribar threshold and resolution.
abstract: Effects of target contrast and background irradiance upon tribar response of optical systems have been investigated. It has been shown that these factors lead to ambiguities in the specification of tribar threshold and resolution for photooptical systems.
