Radiall's latest range of Aerospace Optical Sensors for Luxcis
Author: Rojone Pty Ltd Date Posted:11 April 2022
Radiall’s LuxCis® ARINC 801 fiber optic contacts provide excellent performance in the most severe environments. Flying since 2003, the LuxCis® ARINC 801 is the ideal solution when reliable optical connectivity is required.
The unique design of Radiall's LuxCis® ARINC 801 provides a high density solution that can be integrated in a wide variety of interconnects. This genderless contact is user friendly and easy to maintain. The keyed LuxCis® contact was designed for optimum optical performance in Singlemode APC and provides excellent return loss levels as expected in analogical applications. The pull-proof design can eliminate the need for backshells, reducing the overall weight. Selected as the ARINC 801 standard for aerospace optical interconnects, Radiall’s LuxCis® ARINC 801 is widely used in a variety of harsh environments, including aerospace and military applications.
Radiall has recently released optical sensors that are compatible with LuxCis®. Optical sensing is a proven technique used to measure environmental parameters within many industrial areas, such as power gride and civil engineering.
There are several benefits of optical sensing, including:
- EMI immunity
- ESD immunity
- Multi parameter capabilities
- Integration (embedded sensor)
The advantages make optical sensors very attractive for the aerospace market.
MAIN OPTICAL SENSOR TECHNOLOGIES
Fiber Optic Sensor (FOS) systems measure environmental parameters by analyzing the modification of light propagation in the fiber due to the sensor’s environment.
Distributed FOS use the full length of the fiber as a sensor and rely on the evolution of its scattering behavior, which is measured via optical time-domain reflectometry. They are suitable for long distance and slow changing parameters.
Single-point Fabry-Perot, interferometry-based sensors follow the evolution of environmental parameters at hard to access locations with high sensitivity monitoring. A set of mirrors separated by a cavity detect any micro displacement induced by the environment as it changes the interferometry pattern.
Finally, multi-point Fiber Bragg Grating sensors are the most widely deployed technology. Intra-core fiber gratings can be made along the same fiber in several locations. Any change in the environment will impact the fiber, modifying the grating characteristics and the light propagation.
Optical sensing technology uses multi-mode and single-mode fibers. Angled-polished APC interfaces may be required for more reliable measurements. Optical sensors typically measure strain, temperature and pressure.
As they gain traction in the aerospace market, FOS and the corresponding interconnect solutions must be adapted to the specific requirements of the aircraft environment.
Radiall developed ruggedized contacts in order to successfully support optical sensor integration in aerospace applications.
