this will enable microscope images to be collected from previously inaccessible parts of the human body, while minimizing associated tissue damage. "Light transmitted through an optical fiber is ...

and instead of an optical lens like a normal microscope, it sports a gel pad on the sensing end. By squashing an object into the gel, the device is able to carefully illuminate and image the ...

Such patterns are central to understanding the diffraction limit, a natural effect that sets a boundary on the smallest details that conventional optical microscopes can resolve. (Image: adapted from ...
