A new imaging technique called Speckle Diffraction Tomography (SDT) has been developed that promises to revolutionize the ability to study nanoscale structures. With SDT, scientists can now visualize the 3D structure of nanoscale objects and see how they interact with their environment in unprecedented detail. This new technique has a wide range of applications, from studying the structure of proteins to tracking the movement of particles in fluids. SDT works by combining laser speckle and diffraction patterns to create a 3D image of nanostructures that can be viewed in real-time. This new imaging method promises to provide researchers with a powerful tool for understanding the nanoscale world.
