Abstract

A method based on the line scan of a narrow slit pattern is described for MTF and MRTD determinations. A digital signal analyzer and automatic computer worksheet are utilized for executing this methodology. This single-scan procedure can replace a series of measurements with different sized bar patterns, and it facilitates rapid imaging system characterization for weapons scheduled for intensive hardware-in-the-loop testing. The challenge of this method was to overcome the practical data processing problems encountered. MRTD determinations using the slit-scan method agree very well with conventional bar pattern measurements and has been validated for a variety of imaging sensors. The automatic worksheet analysis determines MTF and both the objective, line scan MRTD as well as the 'eye-brain MRTD' based on a human vision model.
