I have been searching for more information about these new laser "sniffers" since first reading about them here. I found some different links describing the technology today. According to the first article, the trial run at Glasgow airport has been successful. I am wildly optimistic that this will be the future of airport security. I'm gonna kiss the next quantum physicist I meet!
