Holograms that let firefighters see through fire
A digital imaging system could give firefighters the ability to see through heat and smoke, making it easier to detect objects and people.
Although firefighters can use infrared cameras to spot warm bodies, the cameras are often overwhelmed by the heat from extremely hot fires. The new system will use digital imaging to capture infrared signals in 3D and covert them in real time to holographic video. The device will feature an infrared laser, which will be able to penetrate a smoke-filled room and will have a longer wavelength--allowing it to recombine to from large holograms. To turn the static image into video, the laser will send out a pulse of beams that will combine to create the 3D image.
