Christmas in July: Engineers capture gigapixel 3D video of snowflakes
Researchers have developed a lensless chip capable of capturing gigapixel 3D video of melting snowflakes at the nanometer scale. This technology provides unprecedented detail on ice thickness and meltwater behavior, with potential applications for biological cell monitoring.
Why it matters
This advancement in imaging technology offers new capabilities for scientific research in both meteorology and biomedical engineering.

Add as preferred source Six moments of a melting snowflake, captured with the lensless chip. Each frame is a phase image in which color represents the thickness of the ice. The densely packed color fringes are contours of equal thickness that trace the 3D relief of the crystal’s arms. The color washing across the background is a nanometer-thin film of meltwater on the substrate, a change far too subtle for any ordinary camera to see.
