Infrared holography lets rescuers see people through walls, fire, walls of fire (video)

Firefighters already use infrared cameras to find people in burning buildings, but the technology can't distinguish between a person's heat and that of the surrounding fire. That's because a zoom lens is needed to concentrate the infrared rays in a way that enables the apparatus to form a human-readable image. Fortunately, a team of researchers from the Italian Institute of Optics has developed a system that ditches the lens in favor of digital holography that produces detailed 3D images in the darkness. The hardware isn't out of short trousers just yet, but the team is planning to
