Optical science advances non-destructive testing (NDT) through technologies like laser ultrasonics, shearography, and optical ...

Abstract: Phase filtering is one of the core signal processing steps in interferometric synthetic aperture radar (InSAR). In recent years, InSAR phase filtering algorithms have evolved from ...

The OpenFlexture Microscope is a DIY, open-source, 3D-printed microscope built around the Raspberry Pi 4, a Raspberry Pi Camera Module v2, and a choice of optics or various qualities up to lab-grade ...

Researchers have designed and built the world’s first microscope made entirely from 3D-printed parts. And because the open-source plans are already available online, almost anyone can assemble ...

To address the above issues, a scattering power decomposition method based on Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) image and sparse representation theory is proposed.

The world’s first fully 3D-printed microscope can be made in a few hours and for a fraction of the cost of traditional ones. “It’s not just enabling, it’s empowering,” says Gail ...
