| Abstract: | This paper introduces a new type measuring head for operating the liquid level measurement in a gauge glass with lineal array CCD. This measurer is different from other optical systems for size measurement with CCD. According to the fact that different kinds of liquid have different indexes of refraction, we have advanced the method of which we utilize the focusing property of the liquid in a cylindrical vessel to obtain the distinct image of the dividing surface of two different kinds of liquid on lineal array CCD. |
