Someone throws a ball. The other person catches it. Simple, right? No, not really. This is one of the most complex processes science has ever attempted to comprehend, let alone recreate. Inventing a machine to see like the human eye does is deceptively difficult. Not only because it’s hard to [...]
With the advancements in surgical procedures, more operating rooms are performing ‘minimally invasive’ surgeries. What that means is, instead of operating on patients through large incisions, miniaturized surgical instruments are being used to fit through small, sometimes as small as quarter-inch, incisions. The surgical precision lenses in these instruments contain [...]
Sometimes known as photo eyes, photoelectric sensors emit a beam of light that is used to detect the presence or absence of items and equipment, or changes in surface conditions. When the emitted light is interrupted or reflected back by the object, the change in light patterns is measured by [...]
A photonic chip that allows a conventional microscope to work at nanoscale resolution has been developed by a team of physicists in Germany and Norway. The researchers claim that as well as opening up nanoscopy to many more people, the mass-producible optical chip also offers a much larger field of [...]
Although 3D printing is commonly thought of as a new ‘futuristic’ concept, it has actually been around for more than 30 years. […]
Machine vision technology, which allows computers to see and understand their surroundings, is experiencing a dramatic increase in usage.
We live in a day and age where new technologies are being brought to the market at what seems like lightening speed. One advancement leads to another, and then another. New products, based on emerging technologies are continuously being launched. One such technological advance is long-wave infrared – LWIR – [...]
Lidar, short for light detection and ranging – is a key tool for archeologists around the world. Using lidar technology in archeology is quickly taking the place of radar in the attempts to detect more buildings and other structures. […]
Using Raman optical technology, scientists at the University of Twente in The Netherlands can now produce images of brain tissue that is affected by Alzheimer’s disease. The images include the surrounding areas that are already showing changes. […]
The use of motion detectors to keep an eye on the public has been increasing steadily over the past decade. These ubiquitous pyroelectric eyes (passive infrared sensors) can detect everything from thieves breaking into a house to when customers enter the supermarket. Early designs were unreliable, as they would often [...]
