Scientists have been working on a new way to see tiny things in high detail, using a combination of two different techniques that work together like a pair of superpowered glasses.
For decades, scientists have relied on a technique called white light interferometry (WLI) to study the shape and structure of tiny objects. WLI uses a special kind of light to create an interference pattern on a camera, which can then be used to calculate the height and texture of the object’s surface. But WLI has its limitations – it can only capture 2D images, and sometimes struggles with complex or curved surfaces.
Enter optical microscopy (OM), which uses a beam of light to illuminate and magnify tiny objects. OM is great for studying small details, but it often requires the sample to be flat and doesn’t work well with complex shapes either.
Researchers have now combined WLI and OM in a new way that allows them to capture both 2D and 3D images of tiny objects in incredible detail. They call this technique OpticFusion.
OpticFusion uses a special algorithm to merge the information from both WLI and OM images, creating a single, high-resolution image that can show both surface texture and shape. This means scientists can study tiny objects like never before – with precision, detail, and accuracy.
One of the biggest challenges in combining these two techniques was dealing with the fact that they capture different types of information. WLI is great for measuring height and texture, but OM excels at revealing small details like color and pattern. The researchers had to develop a way to reconcile these differences and merge them into a single image.
The result is nothing short of amazing. Using OpticFusion, scientists can now study tiny objects in ways that were previously impossible. They can see intricate patterns on the surface of microscopic structures, or follow the shape and texture of tiny features like hairs or fibers.
For example, researchers have used OpticFusion to study the intricate shapes and patterns on butterfly wings, which are normally too small to be seen with the naked eye. By combining WLI and OM images, they were able to create a single image that showed both the shape and texture of the wing’s surface in incredible detail.
OpticFusion also has potential applications in fields like medicine, where it could be used to study the structure and behavior of tiny biological samples like cells or tissues.
