This technology is based on quasi-stereoscopic imaging using a single digital camera with a rotating aperture minimizing alignment and optical occlusion errors while significantly lowering system cost and complexity.
Processing is performed using compression based local-correlation.
This technology allows moving objects to be imaged, optically measured, and digitally manipulated in three-dimensions. Through the use of a high-intensity ultrasonic field, small spherical tracer particles are formed with two distinct laser fluorescent dyes that exhibit differing temperature dependent emission characteristics. By separating dye emission using narrow band optical filters, simultaneous temperature and velocity of a flow can be obtained. Textured Seal for Reduced Wear Caterpillar, Inc., Dr. Mart Tamre, Hugo Ayala, Jinchul Hong , Ethan Parsons, Hang Qi Investigation of the ingestion of contaminants leading to seal failure and the effects of meso-scale surface contact features. This investigation has resulted in the development of a unique surface technology that greatly extends the life of seals operating in abrasive environments.
