A schematic of a next-generation ultra-thin camera that utilizes metasurfaces, a nano-optical device, to secure light paths: By aligning metasurfaces horizontally on a glass substrate, light reflects ...

Optical instruments are how we see the world, from corrective eyewear to medical endoscopes, cell phone cameras, and orbiting cameras. In this online engineering specialization, you will learn to ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...

Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial resolution of one nanometer. This paves the way for optical microscopy of ...

Particle Image Velocimetry (PIV) and optical flow methods represent two cornerstone approaches in experimental fluid dynamics and motion estimation. PIV employs tracer particles seeded in a fluid, ...
