    A new chromatic confocal microscope images stomach tissue to a depth of about 200 µm with no mechanical depth scanning. The images of excised normal (left) and cancerous (right) human stomach tissue show clear differences, motivating continued development to make the probe suitable for endomicroscopy.
    Researchers create 3D images of biological tissue to depths of greater than 200 µm with a lateral resolution of 2.3 µm—filling the gap between optical coherence tomography and...

    Schematic of the team’s experimental setup; a gold-plated silicon wafer was used as a beamsplitter to reflect a small portion into the reference gas cell, while the rest entered the terahertz cavity.
    A new terahertz laser has potential to bridge the ‘terahertz gap’ for imaging, security, and communications applications.
