    • An apparatus for identifying and measuring in real time substances overlying a surface comprises a plurality of electrodes, a temperature sensor, an electrode control system connected to the plurality of electrodes for defining an electric field, an amplitude and phase measurement system connected to the plurality of electrodes and to the electrode control system for measuring a plurality of currents responsive to the electric field and converting the currents to a measurement set and computer for storing a map comprising a partition of a vector space of predetermined characteristics of substances into regions of profiles corresponding to the substances which could be overlying the surface. The computer correlates the measurement set with the map thereby identifying and quantifying the substances overlying the surface and generates an output signal corresponding to the identity and quantity of substances overlying the surface. A display responsive to the output signal displays the identity and quantity of substances overlying the surface.
    • 一种用于识别和测量表面上的物质的装置包括多个电极,温度传感器,连接到用于限定电场的多个电极的电极控制系统,连接到多个电极的振幅和相位测量系统 电极和电极控制系统,用于响应于电场测量多个电流,并将电流转换成测量组和计算机,用于存储包括具有预定特性物质的向量空间的分区的映射到具有对应于 可能覆盖在表面上的物质。 计算机将测量集与地图相关联,从而识别和定量覆盖表面的物质,并产生与覆盖在表面上的物质的身份和数量相对应的输出信号。 响应于输出信号的显示器显示覆盖在表面上的物质的身份和数量。
