Motion Control Solutions for High-Precision, Large-Field Laser Micromachining
High-precision, high-throughput laser micromachining typically requires galvo scan heads with a short focal length, which in turn produces a small image field, or field of view (FOV). However, a growing number of high-tech manufacturing areas, such as OLED display fabrication, require the processing of workpieces larger than can fit into these reduced image fields, while simultaneously requiring a high level of accuracy and throughput.

High-Speed 3D Inspection with Liquid Lenses
Liquid lenses can be synchronized with high-power lasers and coupled with high-speed image processing for enhanced materials processing and Industrial IoT responsiveness. Many scientific, industrial, and commercial applications demand fast modulation and control over the focus of the lens to enable high-speed illumination and measurements.

Kentek’s Hi Vis Curtain Door
Kentek Corp.
A laser laboratory poses multiple safety hazards that can be harmful to individuals and equipment. Engineering and other control measures must be incorporated into the operation of lasers to maintain a safe environment. Laser safety barriers, either movable or free-standing, are often found surrounding the laser work environment and typically create low light conditions that make it difficult to locate egress points.

Dynamic Speckle Patterns Detect Fires in Harsh Environments
A multi-institutional group of researchers from Denmark and Norway has developed a laser-based system that can detect fires in challenging environments. The new system does not measure the amount of light or its wavelength, but rather how the refractive index randomly fluctuates due to heat convection from the fire.

High-Tech Lidar: The Future Looks Fly
Over 50 years ago, light detection and ranging technology (lidar) found its earliest applications in military targeting and meteorology research, and famously, in mapping the surface of the moon in 1971. But the development of lidar for widespread commercial use is relatively new.

Researchers from Delft University of Technology demonstrated a swarm of tiny drones equipped with optical sensors that can explore unknown environments completely by themselves. The concept, inspired by insect swarms, relies on numerous inexpensive robots with relatively limited sensing and computational techniques, which together are able to explore large areas with greater speed and efficiency than a single larger drone.
