Fiber Optic Rotary Joints Add a Spin to Sensing, Mobile, and Robotic Fiber Systems

To the passing optical signals, fiberoptic rotary joints (FORJs) are nothing more than fiber connectors, which provide connection between one or multiple fibers. Their unrestricted ability to rotate, however, gives them a critical role in many sensing, mobile, and robotic fiber systems such as ROVs (remotely operated vehicles), aerostat radars, submarines, satellite antennae, OCT (optical coherence tomography), mining vehicles, cranes, wind turbines, robotic vehicles, broadcasting (mobile cameras), etc. This article discusses some of the applications where optical rotary joints are indispensable. www.princetel.com Download White Paper

Compact UV Lasers Could Spot Dangerous Substances from a Distance

For soldiers in the field, the ability to identify an object or substance based on how it responds to light could mean the difference between life and death. They could, for example, determine from a safe distance if an approaching person or vehicle is carrying an explosive device or dangerous biological agent.Zhenqiang (Jack) Ma

Selective Laser Sintering System

3D Systems has developed its fastest fab-grade selective laser sintering (SLS) system yet, the ProX 500 Plus. Building upon last year’s ProX 500 release, the ProX 500 Plus continues the company’s efforts to redefine production 3-D printing, adding upgraded speeds, higher print resolution, and an expanded range of engineered composite materials to the line. As with the ProX 500, the ProX 500 Plus delivers injection molding-grade parts without expensive fixed tooling for highly complex and mass customized production. Parts from ProX-series SLS printers exhibit long-lasting, fab-grade durability and functionality as well as smooth surface finish. More detail at http://articles.sae.org/13729.

Laser Measurement

Ophir Photonics’ 1000WP-BB-34 high-power water cooled thermal sensor is designed with the requirement that all materials coming in contact with the cooling water are either copper or nonmetallic. This eliminates the possibility of contaminating the water or corroding the sensor, improving the accuracy and reliability of the measurements. The sensor features a 34-mm aperture and a wide dynamic range, measuring powers from 5 W to 1000 W and energy from 400 mJ to 300 J. More detail at http://articles.sae.org/13730.

RF Photonics for Avionics Signal Processing

The maturity of RF photonic components has reached the point where fiber optic links are being system-tested to replace traditional copper coax links on avionic platforms. Many demonstrations of RF photonic links have been made with traditional and non-traditional modulation formats to improve the RF performance of the link. While the advantages of RF photonic links in regard to size and weight are important, the large instantaneous bandwidth of the fiber optic links is a key driver for the use of this technology in the airframe.
