美国圣地亚国冢实验室研制了一种两级新型光学传感器,这种新型光学传感器在今后或许能用于阻扰高技术窜改器。该传感器可以测量由小型半导体波导产生的光学特征(一种当传感器被干扰时必然会改变的特征)。这种传感器的窜改现象探测能力具有广泛的用途,因为它的尺寸较小,可以固定在诸如集成电路之类可能受到手指撬动影响的器件上。与其它采用光学方法的当发生窜改现象时发报警声的 San Diego, California, United States mound laboratory developed a new two-stage optical sensor, the new optical sensor may be used in the future to block high-tech tweezer. The sensor can measure the optical characteristics created by small semiconductor waveguides (a feature that is bound to change when a sensor is disturbed). The sensor’s ability to detect tampering has a wide range of uses because of its small size and its ability to be mounted on devices such as integrated circuits that may be affected by finger prying. And other optical methods when the phenomenon of tampering alarm
