Spec­ta­tors see the light at uni

Western Suburbs Weekly - - Health -

LIGHT-based tech­nolo­gies have come a long way since the first laser sent out a pulse of light more than 50 years ago.

About 180 peo­ple crowded around a laser show held at the Univer­sity of WA last Wed­nes­day.

The show in­cluded a demonstration by Aus­tralian Na­tional Univer­sity physi­cist Emer­i­tus Pro­fes­sor Hans Ba­chor and Na­tional Science and Tech­nol­ogy Cen­tre co-or­di­na­tor Pa­trick He­lean.

UWA’s stu­dent Op­ti­cal So­ci­ety pres­i­dent An­drea Cu­ra­tolo was a co-or­di­na­tor of the show.

Mr Cu­ra­tolo said the show aimed to pro­mote pub­lic aware­ness of the wide­spread use of op­tics and light-based tech­nolo­gies in science, engi­neer­ing, medicine and arts, in line with the mis­sion of the Unesco 2015 In­ter­na­tional Year of Light.

“Lasers are used in many ways, in­clud­ing as a di­ag­nos­tic and ther­a­peu­tic tool in oph­thal­mol­ogy, at the clin­i­cal and re­search level at the Li­ons Eye In­sti­tute,” Mr Cu­ra­tolo said.

“There is also amaz­ing work in op­tics hap­pen­ing at UWA, for ex­am­ple, at the Op­ti­cal and Bio­med­i­cal Engi­neer­ing Lab­o­ra­tory (Obel) and in the School of Physics at UWA.

The po­ten­tial of lasers was on dis­play at the show.
