Flexible lensless endoscope with a conformationally invariant multi-core fiber [PDF]
, 2019 The lensless endoscope represents the ultimate limit in miniaturization of imaging tools: an image can be transmitted through a (multi-mode or multi-core) fiber by numerical or physical inversion of the fiber's pre-measured transmission matrix.
