Functional near infrared spectroscopic (fNIRS) imaging (pronounced f-nears) has led to a breakthrough in communication with ALS patients who are "Locked-In," meaning they are in advanced stages of the disease where the brain is conscious and functioning, but they are unable to move any muscles, including the eyes.
Like DNA, ribonucleic acid (RNA) is a type of polymeric biomolecule essential for life, playing important roles in gene processing. Short lengths of RNA called microRNA are more stable than longer RNA chains, and are found in common bodily fluids.
Using fiber optics, University of Central Florida (UCF) researchers have developed a technique to monitor, in real time, the formation of dangerous blood clots during cardiovascular procedures.
Novel needle technology developed at the University of Adelaide (UA) uses a tiny fiber optic camera and infrared light to guide neurosurgeons through dangerous procedures. Computer software connected to the needle can recognize blood vessels and alert the surgeon, preventing a potentially life-threatening bleed.
Rice University researchers have refined a Nobel Prize-winning microscopy technique to capture fluorescing molecules at a frame rate 20 times faster than other laboratory cameras.
Raptor Photonics recently launched an additional member to its family of Visible SWIR cameras with the OWL 1280, offering HD resolution for high end long range surveillance, scientific and astronomy applications.
The FDA has approved the VisuMax Femtosecond Laser for small incision lenticule extraction (SMILE) procedures, which are indicated for the correction of nearsightedness in patients age 22 and older. Carl Zeiss Meditec (Zeiss) developed the SMILE procedure as a less-invasive alternative to LASIK and PRK surgery.
PI (Physik Instrumente) L.P. recently announced the newest digital servo controller with 3-channels, offering greater flexibility for miniaturized precision positioning and handling tasks. Applications include precision alignment and automation, semiconductor technology, photonics, bio-nano-technology, metrology, microscopy, micro-manipulation.
The Opera-F is a new optical parametric amplifier (OPA) from Coherent, Inc. that delivers wide tuning, high conversion efficiency, and sub-100 fs pulse duration when pumped by the company’s Monaco high performance ytterbium ultrafast amplifier. The signal output of the Opera-F is tunable from 650 nm to 900 nm, and the idler is tunable from 1200 nm to 2500 nm.
Sierra-Olympic Technologies offers New Imaging Technologies’ (NIT) wide-dynamic-range (WDR), indium gallium arsenide (InGaAs) shortwave infrared (SWIR) sensors and camera systems. This new SWIR imaging product family delivers a dynamic range greater than 140dB in a single snapshot, without any processing or tone mapping. Ideal for biomedical, laser measurements, welding, semiconductor, art inspection, and process control, the NIT WDR sensors’ internal Fixed Pattern Noise correction offers high uniformity images under all lighting conditions.
