ABSTRACT:
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.
