An Optical Illusion is a type of visual illusion where our brain perceives an image that is different from its actual ...

Optical illusions are older than you think. The first optical illusions date back to 20,000 BC and took the form of cave sculptings. Nowadays they are found all over the place – on screens, in books ...

Refractor to reflector, Schmidt-Cassegrain to Maksutov-Cassegrain - this is everything you need to know about the different types of telescopes. When you purchase through links on our site, we may ...

A beamsplitter is an optical device capable of splitting an incident light beam into two. These tools can split both laser and regular light. A beamsplitter can also combine two incoming beams from ...

Figure 1 Comparison of general GPT models (a) and proposed OptoGPT model (b). (c) Convert different types of responses to reflection and transmission spectrum. (d) Illustration of structure ...

Look closely at this picture. At first glance, you can see a big tortoise in the centre of the image. But look closer, and ...

Free-space optical communications (FSOC), which use lasers for data transmission, are a promising approach for achieving high ...

Optical cavities, also known as optical resonators, are structures that confine light within a small volume by utilizing highly reflective surfaces. These cavities allow light to circulate or bounce ...

In a recent study published in Engineering, a team of researchers has made significant strides in understanding optical singularities within photonic microstructures. This research presents a unified ...
