Abstract
The present invention concerns a method of measuring the shape of an injected substance and an automated apparatus for carrying out such a method. In the invention, an optical image of the injected substance, such as atomized fuel mist is projected on a photoelectric converter, and it is converted to video signal. The video signal is sampled at each picture element and the sampled data are memorized in a data memory unit and computed for obtaining a linear luminance distribution function, by determining a line to cut an optical image, then selecting line elements of a fixed length perpendicular to the cut line and computing an average luminance at the individual line elements. The linear luminance distribution function thus obtained stands for a sectional view of a shape of the injected substance mist. And judgment whether the shape is satisfactory or not can be executed on the basis of various shape factors extracted by use of the linear luminance distribution function. The present apparatus can judge, whether, for example, nozzle of a fuel injector is satisfactory or not with high precise.
