【正文】 gorithm to be possible to carry on the fingerprint recognition. This kind of software gathering primitive fingerprint image, and withdraws the pictorial information digitization detail template, then carries on the test, determined withdraws whether the detail template does tally with the reference template. with process Contact type the sensor with delimits the scratching sensor the size and the cost is all dissimilar. The contact pilot is big, usual effective contact face for 1515mm, but rapidly gathers the biggest fingerprint or the thumb fingerprint. This kind of sensor is easy to use, and may the entire fingerprint image by 500dpi (automatic fingerprint recognition standard) the precision carries on the speedy transmission. At present these sensors have pleted the design, and uses in the US government apparatus and the police station carries on the fingerprint recognition. Near future also gradually will use in automobile Shan Chushi not having the key to enter the system, as well as in emerging national security application. This kind of sensor 300 (line) the miniature metal electrode is posed by 256 (row), each row connects to pair of S/On H electric circuit. Fingerprint image succession by a line of gathering, each metal electrode takes the electric capacity extremely, with it contact finger then is electric capacity another extremely. Has a deactivated level in the ponent surface, takes two electric capacities interelectrodes the dielectric sheet. Puts in on the sensor when the finger, in the fingerprint bulge and the indentation can have the different capacitance value in the array, and the constitution uses in an entire image which authenticates. Delimits the scratching sensor is one kind of new fingerprint gathering ponent, the request user has delimited the finger on the ponent. Delimits the scratching sensor the merit is the size small (for example Fujitsu39。 4050 字?jǐn)?shù) 外文翻譯 New fingerprint identification sensor applications analysis Abdtract Fingerprint recognition technology as a sophisticated identification methods have been widely used in various industries. The core ponents of the technology used for sensors, the paper introduced fingerprint recognition technology sensors in the application. Keywords Fingerprint identification Sensors Applications Contact type the sensor with delimits the scratching sensor is two kind of new solid states fingerprints sensor, all is through in touches in the process the electric capacity change to carry on information gathering. This article has carried on the multianalysis to two kind of sensors principles of work and the characteristic, and the int
