High precision and large measurement range are the target of any one three-dimensional scanner. For a line structure light vision sensor, measurement precision depends on its calibration results, i.e.

In materials science, if you can understand the "texture" of a material—how its internal patterns form and shift—you can begin to design how it behaves. That's the focus of the work of Zhenglu Li, ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

In a typical visible laser beam, there are potentially many millions of transverse modes per square millimetre 1, an extraordinary resource if it could be exploited. Yet for many years, only Gaussian ...

A new class of microscopic crystal structures developed at the University of Toronto is bringing high bandwidth optical microchips one step closer to efficient, large-scale fabrication. The structures ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, ...

Norway’s Light Structures has launched a virtual structural health monitoring system designed to help shipowners comply with classification requirements without the use of onboard sensors.The new ...

Independent energy expert and assurance provider DNV and Light Structures AS, a supplier of fiber optic condition monitoring systems based on Fiber Bragg Grating (FBG) technology, have signed a ...

Heavy Steel Frames: Fabricated from hot-rolled steel sections, heavy steel frames are significantly thicker—often above 6 mm—and heavier. They are used in buildings where high load-bearing capacity is ...

On clear nights, the Milky Way appears vast beyond imagination, stretching like a river of stars across the darkness. Yet ...
