Seeing the Unseen Across Ten Orders of Magnitude

Imagine using the same optical technique to map the flex in a 30-ton airliner wing and to chart nanometer-scale irregularities on a virus-templated electrode. In our latest post, we explore how two 1970s-era innovations—Moiré-Holography and Holographic-Moiré—now deliver full-field metrology from meters down to nanometers, powering advances from aerospace composites to next-generation microbatteries and wound-healing nanofiber scaffolds.
