Laser beam tracking for teens: challenge accepted!
Tuesday, May 11, 2021
The Photonic Games are a yearly event which, since 2008, invited nearly 300 students from various high schools in Quebec City to come and participate in a friendly competition at l'Université Laval (http://www.repol.copl.ulaval.ca/jeux/). This competition, in the form of an Olympiad, allows students to familiarize themselves with several scientific concepts related to optics and photonics. The purpose of this activity is to generate an interest toward sciences and especially toward this fascinating branch of physics.
Laser specifications change over time for many reasons and it causes problems accross all industries. Learn about how laser output measurement solves numerous problems in YOUR industry. Download the guide below.
Gentec-EO's high-accuracy laser beam measurement instruments help engineers, scientists and technicians in all sorts of laser applications from the factory to the hospital, laboratory and research center. Learn about our solutions for these measurement types:
Beam tracking turned into a video game
One of the most popular challenges of this event is the Gentec-EO Challenge (a.k.a. Galaxies Bickering). This activity consists of using a laser pointer and a laser beam profiling camera to destroy enemy ships! For this, a LabView program communicates with the BEAMAGE-4M instrument in order to know the centroid of the laser beam on the sensor. The position of the laser is displayed on the game screen and allows the participant to destroy enemy targets. Thanks to the ready-to-use .vi files made available to us by Gentec-EO, communication between the instrument and our program could be established easily and without any technical problems!

Yes, laser beam profilers even have applications in the field of video games! 😉

The Photonics Games organizers graciously accepted to share their LabView program. So if you own a BEAMAGE camera and a LabView licence, download this file and you can try the challenge yourself!
