Abstract

This paper presents a revisit of the traditional measurement of limiting resolution using tri-bar patterns of various digital imaging and image intensifier (I²) systems. Utilizing digital recording of target tri-bar images combined with modern image processing based "line scan" analysis, this reexamination will explore the utility and validity of measuring spatial limiting resolution of various digital electro-optical systems from high light to low light conditions. Also, this paper will provide a detailed line shape analysis of the tri-peak profiles derived from the limiting resolution measurements for low light level ranges provided by these electro-optical systems. Finally, this paper will examine an alternate method for determining limiting resolution using other modern off the shelf digital imaging algorithms/methods and compare this alternate method to the "line scan" method using the traditional tri-bar pattern system. Paper has been cleared by DOD/OSR for Public Release under OSR Ref: 08-S-2710 on November 17, 2008.
