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.
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 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.
