Photonics erase a hindering past

Light is now enabling equal opportunity employment.

In Orange County, California, Judge David Carter has been supporting a program to remove tattoos in order to help convicted offenders to successfully re-enter community and get started on a positive path. The breakthrough will allow them to advance without telltale evidence of a hindering past.

The program, run by Stuart Nelson, Medical Director at the Beckman Laser Institute, University of California-Irvine, has already received kudos from the U.S. Probation Service in Orange County. The process employs laser light to fragment the ink particles so that they are carried away through the body’s immune system.

“This is particularly important to these clients because as they’re trying to re-enter society, acquire a job, establish a new identity and a new career, the stigma associated with having a tattoo can often inhibit that,” Nelson said.

Nelson said they’re fortunate in that most of their clients come with the popular dark blue and black inks that are easily removed by lasers. Removal can be problematic when facing chemical components called organometallic dyes, used to make colored inks.

Nelson has worked with about two dozen probationers so far, removing tattoos located on hands, lower arms and necks.

Nelson’s research focuses on laser and other biomedical optics techniques with applications such as port wine stain removal, noninvasive monitoring of blood with external probes for use by people with diabetes or for monitoring blood sugar in surgery to monitor anesthetics, cancer diagnostics and treatment, and many other life-saving, life-enhancing light-based technologies.

#FacesofPhotonics: Inspired

Guest blogger: Emily Power is a Winter Quarter graduate in communications from Western Washington University, and most recently social media intern for SPIE, the international society for optics and photonics. She is blogging on responses to the SPIE #FacesofPhotonics campaign, to share the stories of SPIE students around the globe.
It is a commonly known fact: students are the future. Around the world, students with ideas, opinions, and innovative minds are preparing for their opportunities to conceptualize and create the next advances for the ever-changing world in which we live.
In the field of optics and photonics, students are making a difference even now, sharing their work and building their networks through conferences such as SPIE Photonics West, coming up next month in San Francisco.
The SPIE campaign #FacesofPhotonics was developed as a showcase across social media to connect students from SPIE Student Chapters around the world, highlighting similarities, celebrating differ…

Grilling robot takes over backyard barbecue

Photonics has already made profound contributions to such areas as medicine, energy, and communications to make our everyday lives more efficient. (Hence the name of this blog.) People in all walks of life benefit from the incorporation of photonics technologies. We look forward to future advancements when the technology may help find a cure for cancer, monitor and prevent climate change, and pave the way to other advancements we can’t even visualize yet.
But here’s a photonics-based invention -- already demonstrated – that breaks ground in a new area: the backyard barbecue. Talk about hot fun in the summertime!
The BratWurst Bot made its appearance at the Stallw├Ąchter-Party of the Baden-W├╝rttemberg State Representation in Berlin. It’s made of off-the-shelf robotic components such as the lightweight Universal Robots arm UR-10, a standard parallel gripper (Schunk PG-70) and standard grill tongs. A tablet-based chef’s face interacted with party guests.

UPDATE! Gravitational waves ... detected!

Update, 11 February: A hundred years after Einstein predicted them, gravitational waves from a cataclysmic event a billion years ago have been observed.
For the first time, scientists have observed gravitational waves, ripples in the fabric of spacetime arriving at Earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein's 1915 general theory of relativity and opens an unprecedented new window to the cosmos.
The discovery was announced on 11 February at a press conference in Washington, DC, hosted by the National Science Foundation, the primary funder of the Laser Interferometer Gravitational Wave Observatory (LIGO).
The gravitational waves were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole. This collision of two black holes had been predicted but never observed.
The event took place on 14 September 2015 at 5:51 a.m. EDT (09:51 UTC) by both of…
