Several image-based biomedical diagnoses require high-resolution imaging capabilities at large spatial scales. However, conventional microscopes exhibit an inherent trade-off between depth-of-field ...

In order to accurately obtain all the information of the observed object, extending the depth of field (DOF) and zooming have always been the research hotspots in the field of microscopy. The DOF of ...

Researchers developed a new smartphone-based digital holographic microscope that enables precision 3D measurements. The highly portable and inexpensive microscope could help bring 3D measurement ...

To observe living cells through a microscope, a sample is usually squeezed onto a glass slide. It then lies there calmly and the cells are observable. The disadvantage is that this limits how the ...

We need microscopes to study most cells. Microscopes are used to produce magnified images. There are two main types of microscope: Glass was developed by the Romans in the first century. Since then, ...
