确定手指的物理特性的手指感测系统、方法和电子设备
摘要：
一种使用手指感测系统(3)确定手指(7)的物理特性的表示的方法，所述手指感测系统包括二维测量装置(13)，该二位测量装置包括多个测量元件，每个测量元件限定测量装置中的测量元件位置，并且每个测量元件包括通过电介质结构与手指间隔开的手指电极。对于测量元件位置中的每个，该方法包括提供测量配置，在该测量配置中：限定测量元件位置的感测测量元件(S)的手指电极呈现感测手指电极电位(VS)；第一不同测量元件(D1)的手指电极呈现第一不同手指电极电位(VD1)；并且第二不同测量元件(D2)的手指电极呈现第二不同手指电极电位(VD2)；基于感测信号获取测量值；并且基于多个测量值来确定手指的物理特性的表示。
摘要（英）：

A method of determining a representation of a physical property of a finger using a finger sensing system comprising a two-dimensional measuring arrangement including a plurality of measuring elements, each defining a measuring element position in the measuring arrangement, and each comprising a finger electrode spaced apart from the finger by a dielectric structure. For each of the measuring element positions, the method comprises providing a measuring configuration in which the finger electrode of a sensing measuring element defining the measuring element position exhibits a sensing finger electrode potential; the finger electrode of a first different measuring element exhibits a first different finger electrode potential; and the finger electrode of a second different measuring element exhibits a second different finger electrode potential; acquiring a measurement value based on a sensing signal; and determining the representation of the physical property of the finger based on a plurality of measurement values.
