Researchers have created a flexible needle-like endoscopic imaging probe that can acquire 3D microscopic images of tissue. The bendability is possible thanks to a new flexible graded index (GRIN) lens ...
(a) Schematics of (a1) the GRIN lens and (a2) the GRIN-lens array, with radial and azimuthal distributions of the fast and slow axes at their cross section, the radius of which can be less than 500 µm ...
Flexible GRIN lens (IMAGE) Optica Caption Researchers have created a new long and flexible GRIN lens (pictured). They used it to create a bendable endoscopic imaging probe that can acquire 3D ...
