Tiny Lensless Endoscope Captures 3D Images of Objects Smaller Than a Cell
- Magazine Article
Researchers have developed a new self-calibrating endoscope that produces 3D images of objects smaller than a single cell without a lens or any optical, electrical, or mechanical components. The tip of the endoscope measures just 200 microns across — about the width of a few human hairs twisted together. As a minimally invasive tool for imaging features inside living tissues, the extremely thin endoscope could enable a variety of research and medical applications.
