    • A biometric device for detecting biological tissue based upon ratiometric measurements of metabolic and/or biochemical intermediates is provided in which a radiation source (103) is electromagnetically coupled to a target region (125). A radiation sensor (155) receives emission signals (128) from the target region as a result of emitted radiation (121) interacting with the target region. A CPU (167) receives a signal from the sensor, and provides a biometric output signal based upon the presence of live, healthy tissue versus sham or dead tissue. Optionally, a conventional, non-metabolism, non-biochemical-based biometric sensor can be incorporated into the present invention, and the biometric output signal is then a result of both the metabolism- and/or biochemical based and non-metabolism non-biochemical-based biometric determinations. A method of performing this biometric analysis is also described.
    • 提供了一种用于基于代谢和/或生物化学中间体的比例测量来检测生物组织的生物测定装置,其中辐射源(103)电磁耦合到目标区域(125)。 由于与目标区域相互作用的发射辐射(121)的结果,辐射传感器(155)从目标区域接收发射信号(128)。 CPU(167)从传感器接收信号,并且基于存在的健康组织与假手术或死组织的存在来提供生物测定输出信号。 任选地,可以将常规的非代谢非生物化学生物测定传感器并入本发明,然后生物测定输出信号是代谢和/或生物化学和非代谢非生物化学的结果 的生物测定。 还描述了执行该生物特征分析的方法。
