optical technology finds applications in medical imaging techniques like endoscopy and optical coherence tomography (oct). endoscopes use fiber optics to visualize internal body structures, while oct utilizes light waves to create high-resolution cross-sectional images of tissues, aiding in diagnosis and ...

Using this principle, it would be possible -- if one wanted -- to pre-determine what image will be displayed when an object is reflected by an angled mirror. History of Kaleidoscopes David Brewster, a Scottish physicist, patented the kaleidoscope in 1817. Photos.com/Getty Images/Think...
Most of the modern color cameras come with a CFA (Color Filter Array) with Bayer BGGR pattern. But the sensitivity of the RGB channel is such that it can capture both thevisibleandIR wavelength. This results in the reduced quality of the final RGB image output owing...
The PIR sensor basic principle of operation depends on the difference in IR energy between an intruder and the background. The sensor detects the presence of an object when its field-of-view is blocked by an object that has a different temperature than the background. As a passive device, ...
UHF RFID operates on the principle of capacitive coupling and uses the so-called backscatter method. Theantennaof theRFID readergenerates an electromagnetic field that induces a current in the antenna of the transponder thereby supplying thetransponderwith energy. The thereby activatedchipof the transpon...

The principle is similar to sanding a table before painting it. Each wafer should be a single crystal of material of uniform composition. Unfortunately, there will sometimes be imperfections in the crystals that make the LED function poorly. Think of imperfections as unmixed bits of flower or ...
When the process flow goes to the resolver, the resolver will generate a query message to be sent to the DNS server. Similarly, the operation of sending a message is not performed by the resolver itself, but delegated to the protocol stack inside the operating system ( The parser itself doe...
Indeed, if a hidden variable theory is in operation, then it governs the whole universe and every process within it, including any deterministic process used to set up the experiment. Since 1982, physicists have performed many Bell tests. Indeed, they have become routine in...
