    Abstract: A non-destructive examination (NDE) system for use on a structural element comprises nano-energetic actuators configured for creating a controlled combustion in response to thermal energy, thereby inducing vibrations in a surface of the structural element. The NDE system further comprises sensors configured for measuring the vibrations induced in the surface of the structural element and generating vibration data. An applique comprises a planar substrate, nano-energetic actuators affixed to the planar substrate, each configured for creating controlled combustions in response to thermal energy, and an adhesive affixed to the planar substrate, such that the applique can be adhered to a structural element. A means of transportation having an accumulation of ice comprises a structural element, and nano-energetic actuators, each configured for creating a controlled combustion in response to thermal energy, thereby inducing vibrations in a surface of the structural element great enough to generate cracks in the ice.

    Abstract: A system for providing active real-time characterization of an article under test is disclosed. An infrared light source, a first visible light source and a second visible light source each outputs and directs a beam of coherent light at a particular area on the article under test. A visible light camera and a visible light second harmonic generation camera, an infrared camera and an infrared second harmonic generation camera, a sum frequency camera and a third order camera are each configured to receive a respective predetermined return beam of light from the particular area on the article under test. A processor receives signals from the cameras and calculates in real time respective spectroscopic signals and compares each calculated signal with each other calculated signal and with a predetermined baseline signal to ensure that the article under test conforms to an expected value.

    Abstract: A system for measuring strain includes an optical fiber having a central portion secured between two fixed points. A first light source outputs light at a first frequency and a second light source outputs light at a second different frequency. The two light sources are both coupled to a first end of the optical fiber. A back scatter detector is also coupled to the first end to receive a return light signal from the optical fiber and outputs a signal based thereon. A forward scatter detector is coupled to a second end of the optical fiber to receive a forward light signal from the optical fiber and outputs a signal based thereon. A processor receives the signals from the back scatter detector and the forward scatter detector and generates an output signal proportional to the strain between the two fixed points based on the received signals.

    Abstract translation: 用于测量应变的系统包括具有固定在两个固定点之间的中心部分的光纤。 第一光源以第一频率输出光，而第二光源以第二不同频率输出光。 两个光源都耦合到光纤的第一端。 背散射检测器还耦合到第一端以从光纤接收返回光信号并基于其输出信号。 前向散射检测器耦合到光纤的第二端以从光纤接收正向光信号并基于该信号输出信号。 处理器从后向散射检测器和前向散射检测器接收信号，并且基于接收的信号产生与两个固定点之间的应变成比例的输出信号。
