The German manufacturer of micro cameras is no bigger than a grain of salt

German researchers have created a microscope with a size no larger than a grain of salt, according to a study published in the journal Nature Photonics.

This invention may cause changes in the field of medical imaging as well as in secret surveillance activities.

By applying 3D printing technology, researchers at the University of Stuttgart have made the above-mentioned 120 micrometer thick camera with three 100-micrometer lens and attached it to the end of a small optical fiber. two hairs.

The team spent only a few hours designing, building and testing the tiny camera. Cameras can record images at a distance of 3mm and then transmit these images through the 1.7m optical fiber that the camera is attached to.

At a size that can be fit on a standard size needle, the camera can be used as a microscope for microscopic examination and imaging of organs. People, including the brain, as well as can be used in security monitoring activities.
