Sensor system that uses embedded optical fibers
| DWPI Title: Sensor system for generating apparent particular velocity of light for indicating detonation velocity of silver acetylide-silver nitrate for deforming portion of airplane wing, has reflective surface being orthogonal to fiber at tip |
| Abstract: Sensor systems including an interferometer system are disclosed herein. In a general embodiment, the sensor system includes an optical fiber that is embedded into a sample, where the optical fiber has a reflective tip. The optical fiber is optically coupled to a sensor and a detector of the laser interferometer system. The sensor system further includes a computing device or circuit that is configured to receive electrical signals generated by the detector. The laser source is configured to emit light, which is coupled into the optical fiber. The light travels through the optical fiber until the light reaches the reflective tip, where it is reflected back through the optical fiber. The detector is impacted by the reflected light, and generates an electrical signal based upon the reflected light. The computing device generates a value that is indicative of a behavior of the sample based upon the electrical signal. |
| Use: Sensor system for generating a value i.e. apparent particular velocity of light, for indicating behavior i.e. detonation velocity, of a sample e.g. explosive such as light initiated explosive e.g. silver acetylide-silver nitrate (all claimed), for deforming a portion of an airplane wing. |
| Advantage: The system allows a mirrored surface of a cleaved end of an embedded optical fiber to prevent light from escaping the embedded optical fiber in an efficient manner. The system achieves time of arrival timing resolution with the system on silver acetylide-silver nitrate explosive exceeded any previously reported timing resolution for silver acetylide-silver nitrate. |
| Novelty: The system (100) has an optical fiber unit embedded in a sample (104). The optical fiber unit comprises an inner fiber through which light travels. A reflective surface is applied to a cleaved tip of the optical fiber unit such that light travelling through the inner fiber is reflected back through the inner fiber by the reflective surface. The reflective surface is orthogonal to the inner fiber at the cleaved tip and arranged in parallel to an exposed surface (108) of the sample, where the sample includes thickness that is defined by the exposed surface and surface. |
