Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in ...

Ptychography is an area-by-area scanning method that uses constant, coherent illumination to scan a region of a sample in several adjacent and overlapping locations. The dispersed radiation is ...

Diffraction spikes, visible in high-power astronomical images, are an intrinsic optical phenomenon in reflecting telescopes, primarily caused by the diffraction and subsequent interference of incoming ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...
