Abstract

Consider a straight row of equally spaced white dots on a black belt running at a constant velocity v over two pulleys. Let the dot spacing be D0. Suppose that the belt is in a darkened room so that even when the belt is at rest the dots are invisible. Let the moving belt be periodically illuminated by some source of intermittent and approximately instantaneous illumination of constant frequency B.
