Seeing a solution: Sully's story

Guest Blogger: Paul Gordon is the current Texas A&M SPIE student chapter president, and PhD student in the Optical Biosensing Lab. 

In the fall of 2016, our SPIE chapter received a unique request; would we be able to help design a visual aid for a young boy with severe visual impairments? It was an easy answer; we would certainly try! A few months later Sully and his family traveled to Texas A&M for a day of activities, and a meeting to assess his condition.

Meeting Sully

As we found out, Sully was a lively kid who didn’t slow down much just because his vision wasn’t so good. He loves running, roughhousing, and all things baseball. It was a blast to meet and work with him and his family.

Meeting the family
What we learned is that Sully’s condition causes him to only be able to see out of a small, solid arc in the central periphery of one eye. With input from his parents, we decided that we would start simply and try to redirect his vision so that he can see objects directly in front of him, eliminating the need for him to crane his neck to the side as he walks.

We did a lot of initial research on his condition, and tried to find commercial options that might be well suited. Unsurprisingly, there aren’t many products out there that help with such a severe impairment.

Thus, we decided on a two-pronged approach. We would reach out to an expert in visual impairments to solicit a prototype prism for visual redirection, and we would construct our own mirror-based redirection system to fit onto his protective glasses.

Seeing in action 

After months of work, we had the pleasure of hosting Sully and his family back at College Station for a follow-up visit. This time, we were able to actually tour behind-the-scenes of the baseball stadium before we got to work, which turned out to be a big hit.

After that adventure, we asked Sully to try on our glasses prototype and navigate simple obstacle courses to test how they work. They took some getting used to, but before long he was able to re-orient so that he could grasp objects directly in front of him.

While playing tee-ball out in the courtyard, he even connected for a nice hit while wearing the new shades. Overall, it was a fantastic visit and a great day for all involved.

The future is bright

Our chapter is continuing to revise our prototype for Sully, and our expert collaborator was able to create and send us a trial prism prototype for him to try as well. We’re encouraged with the progress, but realize that reaching a functional and usable design solution is never a simple process.

In the future, we hope to replace our planar mirrors with off-axis parabolics that will limit distortions and potentially even manipulate Sully’s field of view to optimize for detail or distance work. We’re thankful for the outreach funds provided by SPIE that enabled this work and for the opportunity to use our knowledge to give back to an awesome family.

We’re definitely looking forward to continuing the relationship and developing better solutions as time move on.

Hyperspectral imaging: defense technology transfers into commercial applications

Hyperspectral imaging, like many other of today's technologies, is moving into numerous commercial markets after developing and maturing in the defense sector. While still having a strong presence in defense applications, the technology is now used in chemical detection, food quality assurance and inspection, vegetation monitoring, and plant phenotyping, among others.
For more than 20 years, advances in spectral imaging have been on display at SPIE Defense + Commercial Sensing (DCS). The applications and capabilities of the technology have grown along with the conferences and exhibition at SPIE DCS.
The ability to see more than what is visible to the human eye has always been one of the goals of optical engineers. With hyperspectral imaging they have been able to achieve just that. By accessing the entire electromagnetic spectrum, the sensors are able to image a specific wavelength range, or spectral band, and combine images of multiple bands into one 3D scene.
Through analysis,…

Changing life as we know it: the Internet of Things and cyber-physical sensing

More than 20 billion Internet of Things (IoT) devices are expected to be deployed within the next few years; by 2025, this number may reach as much as 1 trillion connected devices. Driven by growth in cloud computing, mobile communications, networks of data-gathering actuators and sensors, and artificial intelligence with machine learning, this trend will change how we live our lives.
Already we live among connected devices in our homes.

Increasingly, we will also wear them, drive them, and monitor our health via the IoT. More businesses will build, ship, and design products and manage inventory with connected devices. In our cities, transportation, communications, and security infrastructure, and services such as water distribution and energy management will employ IoT applications. Farmers will find many uses, from insuring the health of livestock to increasing crop productivity.
Several conferences scheduled for SPIE Defense + Commercial Sensing 2018 (15 through 19 April in Orland…

Glass ceiling, sticky floor: countering unconscious bias in photonics

Who knew … until last year: Three African-American women working — in obscurity — for NASA as mathematicians played a vital role in the mission that sent astronaut John Glenn into orbit around Earth and brought him back again, in 1962.
Publication of Margot Lee Shetterly's book Hidden Figures and the subsequent release of the acclaimed 2016 film brought the story of the important roles played by Katherine Johnson, Dorothy Vaughan, and Mary Jackson to light for the first time for many.
While their story may have been little known for decades, struggles for opportunity and inclusion are familiar to many women and to members of under-represented minorities or other groups working to make a career in a STEM (science, technology, engineering, and mathematics) field.
Findings on gender equity from the latest SPIE Optics and Photonics Global Salary report indicate that women in the field lag behind men in salary and in representation in management and senior academic positions.
The cost…
