Four methods for near real-time measurement of the modulation transfer function (MTF) of electronic displays are presented. The methods are based on measuring the display’s response to an edge, periodic bar-patterns, line and whitenoise stimuli. Although all the methods yield practically the same result, they require different data acquisition time and different degrees of human intervention while analyzing the acquired data. The paper presents a comparison between the four methods in context of the time required to implement each and cites implementation issues that need to be addressed in order to achieve real time data analysis and presentation.
