Navigating the Options for 3D Imaging
While 3D imaging in machine vision has been applied in key use cases for many years, use of the technology has recently grown and expanded, making it increasingly common in a wider range of applications. The best practices that can help to ensure a successful 3D imaging project involve component specification and project implementation. However, it’s important to start with an overview of 3D imaging and a review of the methodologies available in the marketplace.

New Sensors and AI Optimize Laser Welding
Welding is an ancient technology. Five thousand years ago, Egyptians used it to join copper water pipes together. Over the centuries it evolved into an essential technology to fuse various types of metals as experienced welders learned to optimize the process by observing and reacting to colors in the material and the flames. Welding technology has made more progress in the last 50 years than it did in the preceding millennia. A crucial part of this development relies on optical sensing of process parameters far beyond what our eyes can perceive.

Adaptive Optics Elevates Ground-Based Telescopes’ Image Quality
After starlight enters the atmosphere, it passes through layers of turbulence that grant the light a twinkling or flickering effect when viewed from Earth. This turbulence also affects the quality of images taken with ground telescopes. This effect can be mitigated with adaptive optics, which serve to correct the distortion caused by atmospheric turbulence.

Researchers from the Fraunhofer Institute for Laser Technology, in collaboration with colleagues from Fraunhofer ISIT and IST, developed a CMOS-compatible deposition and laser crystallization process for the production of micro-electromechanical systems. In contrast to other common processes, the method eliminates the need for wires and solder joints — an advantage that can significantly reduce the component size and enhance the sensor performance.
