| 1. | The new fingerprint sensor features enhanced imaging capabilities , electrostatic discharge ( esd ) performance and improved ruggedness to provide superior levels of accuracy and reliability for fingerprint authentication . when a finger contacts the iguard fps110 sensor surface , the sensor measures the capacitance at each pixel in the 300 x 300 array in the sensor s surface . differences in capacitance correspond to the ridges , valleys and pores that characterize a unique fingerprint
感应器上,在感应器保护表层之下的300x300列阵电容感应晶片( 90 , 000感应点)便会探测你手指的电容,因皮肤表面凹凸和感应器距离不同,所以有不同的电容值,用此来分别指纹,在感应器保护表层之下的300x300列阵电容感应晶片( 90 , 000感应点) ,其间距是50 m 。 |
