Researchers used consumer-grade 3D printers to create sub-$1 optical lenses that enable super-resolution nanoscale biological ...

Researchers have shown that consumer-grade 3D printers and low-cost materials can be used to produce multi-element optical ...

Estimating π with “fake circles” using Python. This short shows how to simulate the geometry, calculate the approximation step by step, and see how accuracy improves as the model gets refined. #Python ...

Abstract: High-resolution and amplitude-preserved imaging is crucial for mapping impedance interfaces and identifying hydrocarbon reservoirs in the subsurface. Although elastic reverse-time migration ...

Get up close and personal with life using a digital microscope Take a closer look at the plants, foods and textures around you using an microscope that connects to your phone, tablet or computer.

Abstract: We proposed a DHM system with improved spatial resolution compared with that of the polarized camera-based DHM system by employing a liquid crystal phase modulator (LCPM). The LCPM-based ...
