Biomedical engineers at Duke University have discovered a way to detect signs of cancer on a cell-by-cell basis using a technique that involves two lasers and a camera. The technique, using biomedical lasers and cameras, can assess an individual cell’s stiffness using patterns that appear within its internal structure. Several [...]
Researchers at the U.S. Naval Research Laboratory (NRL) have demonstrated for the first time that they can discover cracks in the ship’s structure by detecting acoustic emission from cracks in riveted lap joints. Optical Sciences Division, in collaboration with the laboratory’s Material Science Division, used a distributed feedback fiber laser-acoustic emission sensor which [...]
CHemCam - identifying and targeting rocks - laser technology/laser lenses On August 5th, 2016, NASA’s newest rover arrived on Mars carrying a host of state-of-the-art instruments, including the head-mounted, rock-zapping lazer called ChemCham. Chemistry and Camera complex (ChemCam) is a suite of remote sensing instruments on Mars for the Curiosity [...]
Renewable energy is prized in many areas of the country and you will see wind turbines being installed on hillsides to harness the wind to create energy. In Uruguay wind turbines are being installed with a lidar system to monitor the performance of the turbines and provide the turbine owners [...]
Lasers are a part of the technology that is used to study the movement of water through soil; a technique called soil hydrology. Through this study, soil scientists can more accurately predict water flow. Recently, researchers at the University of Kansas used a multi-stripe laser triangulation (MLT) scanner to help [...]
Automobile technology is always evolving and safety technologies are along for the ride! Lane departure warning systems are a new technology that is designed to prevent high-speed accidents. The way the lane departure system (LDW) technology works is by monitoring the lane markings on the highways and sounds an alarm [...]
Details make the difference, especially when making precision cuts. Having a finished product that is polished and clean-looking is the end goal for manufacturers and they are finding the best way to attain that goal is through the use of a laser cutter. Laser cutting tools provide manufacturers the ability [...]
Researchers had been looking for ways to quickly and easily detect bacterial growth in food and discovered that tunable diode laser absorption spectroscopy (TDLAS) does just that. The TDLAS allows for accurate, fast and noninvasive ways to measure the levels of bacteria in blood supplies, food and other products that [...]
Amplifying an entire wavelength grid at one time and being able to convert it into a channeled electrical signal, regenerate it, convert it into an optical signal and eventually multiplex all of the channels into a single optical fiber is now possible with tunable lasers. A tunable transmitter provides relief [...]
The use of medical lasers is not a new technique employed in hospitals, but there are new applications being developed with regularity that assist with drug delivery, gene therapy, nerve repair, dentistry and oncology. In 1967 a researcher in Budapest, Hungary recognized that a ruby laser could stimulate faster hair [...]
