Paper Abstract

In the aircraft industry, rigorous testing of dynamic seals for hydraulic actuators is necessary. There is a requirement to test the seals inside the actuators. The difficulties posed by this requirement to remotely sense and acquire the images of the dynamic seal can be reduced by the use of fiber optics. The fiber optics transmits the images of the seal inside the actuator to the camera. The various schemes using fiber optics for this purpose have been presented. The images were digitized using a computer vision system. By using different traditional image enhancement techniques, the acquired images were analyzed and varying results presented. Some of the results enabled surface imperfection such as edge cracks to be identified, with the images of other edge deformation of the seal sharpened and easily interpreted.
