Abstract
The motion of a kinescope panel on a lighthouse is made intermittent by dividing the total excursion distance into intervals. Each interval is segmented into a move time and a dwell time which are expressed as move counts and dwell counts per interval. The counts per interval are changed in accordance with the required exposure time and the intensity of the exposing energy source.
