Six radial targets having different line width to space width ratios were made. The effect of the ratios on the phenomena of spurious resolution and resolving power was studied on a fine grain and a coarse grain film. Spurious resolution patterns were undetectable when the dark space exceeded five times the width of the bright line. Resolving power values reached their maximum when the target contained lines that were one-fifth the width of the dark spaces between them.
