A quirk in scientific 3D modeling has led to the discovery that laser light can — under the right circumstances — cast its own shadow. The finding challenges our current understanding of what ...

The approach uses lasers and holograms to detect misalignments as small as 0.017 nanometers. Researchers at the University of Massachusetts Amherst have developed a new method for aligning 3D ...

The scanner uses laser light to create centimeter-precise 3D models of individual trees, enabling scientists to track growth and structural changes with unprecedented detail. A similar research ...

“The technology uses less expensive light sources as simple as a laser pointer ... and health care. Femtosecond laser two-photon polymerization is widely used for 3D nanostructure fabrication.
