In the investigation of oculomotor systems and especially in the mathematical descriptions of them as pursuit, tracking and stabilizing systems,
the need arises for a more exact knowledge of the mechanics of the
eyeball, the extraocular muscles and the supporting tissues of the orbit,
particularly of the way in which these factors permit the globe to respond
to the efferent discharges arising in the oculomotor nuclei.
In 1954
Westheimer proposed that the eye moved in a saccade by the application
of a step function of net muscular force.
He further proposed that the
mechanical system was of second order, slightly underdamped and had a
natural resonant frequency of about 120 radians per second (19 c
