A newly developed fiber-optic microphone demonstrates how light-based sensing can overcome the limitations of conventional electronics in extreme environments. A team of researchers has built a microphone so small it fits inside a strand of pure silica fiber, yet it can pick up ultrasound far above the limits of human hearing. Because the device is […]Technology,Materials Science,Optica,Optics,Optoelectronics,Photonics#Microphone #Glass #Survive #Extreme #Heat #Electromagnetic #Chaos1770854228
