Reliable Machine Vision Systems: Influence of Noise and Light Source
Apr 1, 2008 — Many inspection tasks, such as those of displays for the flat screen industry, can be performed only by machine vision systems. And these systems make the performance of tasks such as manual sorting inspection cheaper, easier and more reliable. However, experts emphasize that much of the potential of machine vision is not being used and that an effort must be dedicated to research and development of inspection systems to support the promising field of microsystem technology. Figure 1. This...
Super-Tiny Mach-Zehnders Assembled with Nanofibers
Apr 1, 2008 — Mach-Zehnder interferometers find application in fields ranging from telecommunications to medical diagnostics to spectroscopy. Investigators have constructed the devices using free-space mirrors, optical fibers, photonic crystals and microfluidic...
Visualizing a Laser’s Polarization
Apr 1, 2008 — One of the oldest tricks in the book is checking a laser beam’s polarization with a microscope slide: You stick the slide, oriented at Brewster’s angle, into the beam and then rotate it around the beam axis until the reflection disappears. The...
Watching What Happens During Attoseconds in Solids
Apr 1, 2008 — New insight into ever-smaller structures of matter and their ever-faster dynamics holds great promise for pushing the frontiers of many fields in science and technology. The speed of electronic processes is determined by the separation of the...
