Collaboration is the Key

A major part of the meeting are the breakout group discussions. Participants were assigned to one of five potential application areas: Commercial Security Cameras for use in Homes, Businesses, Stadiums or Airports; UAV Surveillance Imaging; Near IR Imaging for Intra-cranial Bleeding Detection and Localization; Soldier-scale Situational Awareness; and Astronomical Imaging Applications.

OSA Incubator: Implications of Compressive Sensing Concepts to Imaging Systems

While the hot topic of DC in general might be the Cherry Blossom Festival, here at OSA headquarters we’re focusing on compressive processing.First, what is an Incubator?  The OSA Incubator Program began in 2011 and this week’s OSA Incubator Implications of Compressive Sensing Concepts to Imaging Systems is the 13th Incubator to date. Each Incubator differs not only in topic but...

The Role of Chance in Biomedical Imaging

Much of my work as a postdoctoral trainee at Tufts University has focused on utilizing endogenous sources of optical contrast to assess tissue development and disease. To this end, our lab has utilized non-linear optical microscopy to non-destructively characterize tissue organization and metabolic function with an emphasis on understanding and detecting stem cell differentiation and...

OSA Topological Order with Photons Incubator: Facilitating Discussion of this Nascent Field

Greetings from the 12th installment of OSA Incubator meetings, the OSA Topological Order with Photons Incubator! Hosted by Steven Girvin, Yale University, United States; Mohammad Hafezi, Joint Quantum Institute, United States; Karyn Le Hur, Ecole Polytechnique, France; Jacob Taylor, National Institute of Standards & Technology, United States; the meeting will span two days, involving formal...

How do you make a topologically interesting system with light?

Quantum superposition states are immensely delicate things - any interaction with the environment can cause them to decohere. This poses a significant problem for quantum computing, where information would need to be stored within quantum states for relatively long periods of time. A promising way to isolate a system exploits the topology of the system, known as 'topological protection'...

What lies ahead for topological photonic systems?

The final day of the Topological Order with Photons Incubator saw several more proposals for systems that could support topological edge states. Metamaterials are a promising environment, and talks were given by Alex Kanikaev and Gennady Shvets on fabricating bianistropic metamaterials to emulate electron spins and topological insulators. Na Young Kim and Alberto Ano laid different schemes...

Salt and Pepper (Noise): Key Ingredients for Imaging Blood Flow

We’ve all experienced that “salt-and-pepper”, or white noise when our favorite television show cuts out on us. Well it turns out that similar “speckle” patterns are also seen when projecting laser light onto biological tissue, owing to interference patterns of the monochromatic light source. Now you might say, “so what!” and that’s probably what...

A Woman's Place is in the Lab

As a female engineer, one becomes accustomed to being a minority: in the lecture theatre, in the graduate lab and in the workplace.  We have come a long way from the days when women scientists were an anomaly, but the number of women choosing STEM courses and careers at the undergraduate and graduate level still lags behind our male counterparts.  But to grow female representation in...

Day 1 continued: Learning to See Through Walls

Is it possible to look inside an object using only light reflected off the front?  Can you transmit more light through an attenuating medium by making it even thicker?  Could a bank verify your identity using the pattern of light scattered off your teeth?
