Light Up the Outback - Bright Lights for Bright Minds

By Macquarie OSA Student Chapter | Posted: 30 September 2016

In August, two physics PhD students from Macquarie University, Australia spent a week visiting regional and rural high schools around New South Wales. Eight different schools were visited over the course of 5 days, in a loop of almost 2000 kilometres. Over 450 students and their teachers participated in the sessions. Each visit to the schools had three parts. A short talk on optics or laser and communications was given first. The students then got the chance to interact with a range of optics experiments, including a thermal camera, Schlieren camera/mirror assembly, laser telephone, laser minigolf, laser music player, laser ray optics, diffraction grating glasses, and hand-held spectrometer. Just about every school had a different ‘favourite’ experiment, with students and teachers all getting involved.

Understanding Multi-Photon Bio-Imaging

By Karlsruhe Institute of Technology, OSKAR | Posted: 6 September 2016

On the 29th of June 2016, Optics Students Karlsruhe e.V. (OSKar) hosted an OSA Traveling Lecturer at the Light Technology Institute (LTI), Karlsruhe Institute of Technology (KIT). The lecture program is sponsored by The Optical Society. This year we are honored to have invited the OSA Fellow, Professor Chris Xu from Cornell University, USA to fly to Karlsruhe, Germany and give a presentation on multi-photon bio-imaging to the students and professors in KIT. The professor was invited by OSKar’s president, Xiang Gao. They knew each other since 2014 summer in Peking, China and still keep in contact. Though the main focus of the talk was specialized on the improved multi-photon imaging techniques, there are many students and professors of different backgrounds and research areas who attended. Professor Xu showed us the latest achievement in his laboratory, i.e. the deep imaging down to millimeter below the surface of a living mouse’s brain by using 2 and 3-photon-absorption. In the images he showed, we could clearly see the structure and topology of the neurons, which were not yet discovered to such detailed level before. That should be attributed to the multi-photon in vivo bio-imaging methods. The audience was amazed by the excellent research work in Professor Xu’s group and attractive presentation style.
