Human flesh is opaque. As any good dictionary will tell you, that means it has the quality of “not transmitting light; being impenetrable to sight.” Well, forget that: scientists now can use light to see inside objects that were traditionally off-limits to the human eye—including our bodies.
Of course it’s already possible to use X-rays, MRI, ultrasound and the like to peer inside human beings, but results are never as crisp and clear as those acquired using visible light imaging. Not only that: optical wavelengths also interact with organic molecules—the one we’re made of—so visible light could also contain vital information about the tissue it travels through. It might reveals abnormalities in cells, say, or use information about bodily functions—something that other imaging techniques, such as MRI, resort to complex chemical tracers to achieve. And, perhaps most importantly, it’s also non-ionising, which is to say that, unlike X-rays and CT scans, it doesn’t increase cancer risk at the intensities used for imaging.

The international year of light is a global initiative to increase awareness and education on the many ways light effects our world. Rochester, being a huge player in the world of optics, has a great website if you want to get involved in activities surrounding the international year of light. Check out the site:
A new contact lens is being developed by Dr. Eric Tremblay (a designer) from the Swiss Federal Institute of Technology that may help people see that suffer from age-related macular degeneration. The contact lens features an inbuilt telescope. Read more here

There are many types of thickness measurement- one of those being ultrasonic thickness measurement. Ultrasonic thickness measurement has many benefits, but falls short in a few critical areas where optical thickness measurement excels. Here are the details:

One of our rock-star engineers, Clark, sent me this video today because he thought it was really interesting- it shows how fiber optics are made. I’d have to agree that it is a pretty fascinating video.
This video was featured on the Discovery Channel’s “How It’s Made” television series in an episode about fiber optics. In this particular episode, employees take the viewer on a guided tour of the Browning, Texas Corning plant where fiber optics are manufactured.
One of the most prevalent measurement devices in a medical balloon or catheter manufacturing facility is the micrometer gauge. It is simple and inexpensive. But, this measurement technique is subject to a high degree of operator variability. Another limitation is that it measures total thickness only, and not the actual individual wall thickness. Furthermore, a micrometer compresses the measured part, and must, by design, come into contact with the material. The micrometer does not provide engineers with the precise and detailed information they need to develop and improve production processes. What other issues are there? Read More
This is a fun summary of 10 great new ideas in the medical device industry that could really change your life. As we look back on 2014 and forward to 2015 we should keep these technologies in mind. All of them use photonics at their core.
There are technology breakthroughs, and then there are jaw-droppingly amazing technology breakthroughs.
We at Qmed have seen plenty of incredible technologies come across our radar this year. Here are 10 that especially impressed us:
Amazing work going on at U of R. The official New York Photonics blog authored by, Thomas Battley elaborates that: “Researchers in Rochester, NY are finding ways to understand some of the mysteries of space without leaving earth.” Read the full article here.
