Goal-line technology gets a workout at FIFA Women's World Cup



Seven cameras track the ball from every angle. (FIFA image)


The 2015 FIFA Women’s World Cup, currently underway in Canada, is drawing record television audiences around the world. It’s also another milestone for goal-line technology (GLT), which is quickly gaining acceptance.

In the group stage, which ended on 17 June, FIFA reports that GLT was used to award goals by Mexico in a 1-1 draw with Colombia, by Thailand in a 3-2 win over Ivory Coast, and by Costa Rica in a 2-2 draw with Korea. Also, it confirmed a save (no goal) on a header by Meghan Klingenberg in the USA-Sweden game, a scoreless draw.

The Hawk-Eye GLT system consists of seven cameras positioned strategically at each end of the stadium, to track the ball precisely from every angle. Within one second of a play at the goal line, a signal is relayed to the referee’s watch to confirm the goal. It is reputed to be accurate within 1 mm. Hawk-Eye was selected for this year's tournament in March.

Last year’s men’s World Cup in Brazil was the first to use GLT – with a different system, GoalControl, which uses a similar seven-camera setup. France was the first to benefit from it, when an inconclusive goal was confirmed in a match against Honduras. Hawk-Eye had competed for last year's men's World Cup, but lost out to GoalControl.

SPIE Newsroom explored goal-line technology in 2012 when the technology was being considered by FIFA's rule-making body, the International Football Association Board (IFAB).

#FacesofPhotonics: Rising Researcher Alina Zare

SPIE's #FacesofPhotonics is sharing the story of Alina Zare, Associate Professor at the The Machine Learning and Sensing Lab at the University of Florida. Dr. Zare was recognized as a 2018 Rising Researcher for her work in Electronic Imaging & Signal Processing, at the SPIE Defense + Commercial Sensing conference.

This program recognizes early career professionals who conduct outstanding research in the defense, commercial, and scientific sensing, imaging, optics, or related fields. If you want to learn more about the program, the details are here.

Enjoy the interview with Alina!

1. Tell us about when you first became interested in optics and photonics. In my senior year of  undergraduate studies in computer science, I was taking an Image Processing elective.  I really enjoyed the course, and the professor for the class, Dr. Gerhard Ritter, encouraged me to do some undergraduate research.  
So I joined Dr. Paul Gader's research lab as a undergraduate researcher where I he…

Lighting Their Way

It's a feast for the science-curious senses: in June, two cohorts of two dozen middle-school girls came together for the free, STEM-focused, four-day-long Physics Wonder Girls Camp sessions organized by Dr. Roberto Ramos, associate professor of physics at the University of the Sciences in Philadelphia.

The girls studied the properties of light, built telescopes, designed and engineered submersible robots, and learned about scientific professions directly from the experts: nanoscientist and Chair of Bryn Mawr College's Physics Department Dr. Xuemei Cheng; INTEL software engineer Dr. Marisa Bauza-Roman; and several female food scientists from Puratos, a global company working with bakers and chocolatiers to assess the best ways to improve their products, all came and talked about their professions, answering questions and interacting with the campers. Plus, they got to be on TV!

The camp was initially inspired by Dr. Ramos' daughter Kristiana who expressed interest in the s…

#FacesofPhotonics: University of Arizona Cancer Researcher Kelli Kiekens

SPIE’s #FacesofPhotonics is a showcase across social media that connects SPIE members in the optics and photonics community around the world.

It serves to highlight similarities, celebrate differences, and foster a space for conversation and community to thrive.

This week on #FacesofPhotonics we are sharing the story of Kelli Kiekens, researcher at the University of Arizona in Dr. Barton's lab. From searching for a way to detect cancer earlier, to ballroom dancing, Kelli is a woman of many talents.

We hope you enjoy her interview.

1. Tell us about when you first became interested in optics and photonics. During my undergraduate education, my senior design class concentrated on various topics within optics. The group project for that semester was a study of holography where we created different types of holograms using a few different methods. 


We could then compare the quality of the holograms and see which were better. The part of this project that caught my attention is when we …
