Abstract: The objective of this paper was to detect of impurities in liquid materials. The application of the technique to the assessment of single object and the appropriate starting material is discussed. Basic theory will be used to show how the high frequency field imaging is transformed into a time varying charge distribution at three transducer faces. It will also be shown that this gives a critical assessment of the factors limiting the performance of this transducer. The donor density is assumed to be variable of the coordinates. This transducer will be used as a radio frequency photo sensor device in an optically scanning system, to improve the quality of imaging. This invention can detect accurately the impurity contents of unknown object in refined metallurgical Grease liquids (such as glycerol and glycerin). A digital signal processing technique is used to improve the quality of image. A digital correction technique will be shown to offer a simple and convention means of eliminating the effects of system non-uniformities. This technique is simple, low-cost and suitable for industrial applications.
