Abstract
BASIC COMPONENTS OF THE EQUIPMENT: - 1 sensor consisting of a plurality of photosensors arranged linearly at regular intervals; - 1 circuit capable of selecting the data arriving from a single photosensor (switch); - 1 circuit capable of providing a measurement of the intensity of direct and reflected light falling on the photosensors. OPERATING PRINCIPLE: An opaque object with a flat surface, resting on a uniformly illuminated plane which contains within it a line of photosensors equidistant from each other, obscures the number of photosensors corresponding to the dimension of the object, thus making it possible to derive the said dimension.
