Design of Graded Index Fiber Lenses for OCT Applications

            A fiber-optic probe, for optical coherence tomography (OCT) applications, typically includes a short section of graded index (GRIN) fiber fused onto a single-mode (SM) fiber. The GRIN fiber acts as a lens to focus the output of the SM fiber and to collect the reflected light from the sample. In this paper we use a beam propagation method (BPM) to analyze the output beam characteristics such as beam radius and working distance, and then compare these with measured results. With this tool we can design a GRIN fiber lens to achieve a long working distance without degrading the system performance.

Carbon Fiber Reinforced Polymers - How Fiber Lengths and Loading Define the Achievable Properties and Dictate the Manufacturing Techniques

The Webinar will look at the properties of thermoplastic composites. Focusing mainly on carbon-fiber filled composites, we will show how the geometry of the filler, as well as the amount of filler, affects the properties of the finished article. The filler properties also generally determine the available manufacturing techniques that can be used.

Testing Astronaut-Controlled Surface Robots from the International Space Station

The National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) are currently developing robots that can be remotely operated on planetary surfaces by astronauts in orbiting spacecraft. The primary objective of this work is to test and demonstrate crew-controlled communications, operations, and telerobotic technologies that are needed for future deep space human exploration missions. Specifically, NASA’s “Human Exploration Telerobotics” (HET) project and ESA’s “Multi-Purpose End-To-End Robotic Operations Network” (METERON) project are complementary initiatives that aim to validate these technologies through a range of ground and flight experiments with humans and robots in the loop.

Next Generation Non-Destructive Material Analysis - How Handheld FTIR Spectroscopy is Changing Damage and Contamination Analysis, Coating Evaluation, and Material Identification

Handheld FTIR spectroscopy provides a range of new capabilities for non-destructive testing of composites, coatings and polymers. This technique allows the user to take the instrument directly to the object requiring analysis, regardless of its location or size—eliminating the need to transport an object or sample to a traditional lab. Measurements can be made in situ and in real-time, enabling greater flexibility in understanding what and where to measure. It also means that it is not necessary to excise a sample from the object, making handheld FTIR a truly non-destructive testing solution.
