Application-Specific Machine Vision Simplifies Aircraft Maintenance
Machine vision systems, however automated, do not exist in isolation. They must augment and intelligently interact with human operators. Workflows can benefit from 3D optical vision systems. In particular, vision systems technology shows significant promise to improve aircraft inspection efficiency while providing operators with a better understanding of airframe integrity and safety. However, to deliver these gains to an airline’s bottom line, the vision system must coexist with and empower the technician/engineer.

Harsh-Environment Fiber Optics for Aerospace
In its most basic form, bare optical fiber consists of a silica core and a cladding whose indices of refraction vary slightly. However, bare fiber is not very useful beyond a laboratory setting because its performance is highly susceptible to its environment. An outer coating is usually added to provide extra flexibility...

Manufacturing High-Performance Mirrors
When it comes to long-range, multispectral optical systems, large mirrors play an integral role; there are tens of thousands of optical units containing large mirrors around the globe. With minimum diameters starting at 200 mm, the largest mirrors range from 8.2 m in diameter (single mirrors) to over 10 m (segmented). They take many shapes — spherical, aspheric, parabolic, or freeform — and are used for a wide spectrum of light, including visible, UV, and IR.

Protective Coatings Extend Optics Lifetimes
Wed, Oct 10, 2018 1:00 PM - 2:00 PM EDT
From military airborne applications to harsh industrial uses, optics can be subjected to considerable environmental abuse over their expected lifetime. That lifetime can be extended by the use of protective coatings. In this one-half hour webinar, you will learn about the challenges to the integrity of optics due to abrasion, corrosion, oxidation, and other phenomena. The speaker will also provide an overview of the types of protective coatings that are used and their deposition technologies, and he will tie the various coating types to the environmental challenges they are intended to address. The webinar will cover environmental testing and durability, and touch on other coatings that have functional properties besides protection.
