    Self-sweeping laser could dramatically shrink 3-D mapping systems

    A new approach that uses light to move mirrors could usher in a new generation of laser technology for a wide range of applications, including remote sensing, self-driving car navigation and 3D biomedical imaging. A team of University of California, Berkeley, engineers led by Connie Chang-Hasnain, a professor of electrical engineering and computer sciences, used a novel concept to automate the way a light source changes its wavelength as it sweeps the surrounding landscape. They report their findings in the journal Scientific Reports , to be published Thursday, Sept. 3. The advance could have implications for imaging technology using LIDAR, or ...
