French researchers from the Institut Langevin have developed new technology to see-through opaque surfaces. According to PSFK, "The scientists used a laser, a digital camera and a projector to extract images from light passing through a solid surface by interpreting how the surface makes the light scatter."
What these Institut Langevin researchers have discovered could potentially replace X-ray and ultrasound technology in medical procedures.
