The measurement technique of the aspheric surface is mainly for the surface form and parameters. The surface form is the three-dimensional distribution of the surface in the spatial domain. The ...

Optical 3D metrology enables fast, non-contact surface roughness measurement of defects and roughness for precise ...

Measuring blood flow in the brain is critical for understanding response to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. Obtaining such ...

Wide bandgap semiconductor materials are highly useful in power electronics due to their ability to work at high temperatures, power, and frequency. Gallium nitride (GaN) is a wide bandgap ...

Sneezes, rain clouds, and ink jet printers: They all produce or contain liquid droplets so tiny it would take several billion of them to fill a liter bottle. Measuring the volume, motion and contents ...
