Abstract:

This patent discloses an optical system limiting resolution determination arrangement employing sinusoidal intensity modulated bar pattern input stimuli including two sequences for determining the modulation transfer function MTF component of limiting resolution one of these and the disclosed aerial image modulation AIM curve determination are based on sinusoidal intensity modulated bar patterns, while the other MTF determination uses a Heaviside edge function stimulus and a sinusoidally determined aim curve. The disclosed limiting resolution is especially useful in the consideration of aerial image devices such as cameras.
