Time-Domain Terahertz Sensing Does a Better Job Measuring Critical Product Parameters in Medical Tubing

As the demand for more complex, precisely controlled medical tubing increases, it is increasingly important to have monitoring methods that can provide the full range of product information necessary for the manufacturers to profitably manufacture and validate their products. Most high-performance medical tubing products are produced by extrusion processes. A hopper of raw polymer pellets feeds into a heater element to melt the material to…Read More

Luna Innovations Provides Comprehensive Solutions for OCT Systems

Optical Coherence Tomography (OCT) image resolution, which can be 100 times better than conventional ultrasound, has profound implications for the diagnosis of internal problems in biological tissues as well as inorganic samples. OCT has become increasingly popular for medical applications such as non-invasive opthalmological imaging, endoscopic gastrointestinal tract imaging and diagnostics for coronary intervention. Fiber-based OCT systems require precise polarization management, accurate delay control, fast wavelength…Read More

Distributed Vibration Measurements Extend Capabilities of Key Monitoring Applications

Monitoring applications have driven the widespread adoption of fiber optic sensors in many industries, spanning civil infrastructure, geotechnical applications, energy systems and general manufacturing. New fiber optic accelerometer technology that provides distributed vibration measurements can extend capabilities for structural health monitoring, dynamic analysis, security and other monitoring systems. These applications have typically utilized some combination of strain, temperature, pressure and displacement monitoring, which are mostly…Read More

Polarization Extinction Ratio Measurement Methods and Applications

Polarization extinction ratio (PER), a measure of the degree to which light is confined in a principal linear polarization mode, is an important performance parameter for many lasers and for PM fiber components and systems. In addition to its use in characterizing finished components, PER measurement is necessary for active alignment of PM connectors. Common methods for measuring PER have different capabilities and limitations. An…Read More

Techniques for Measuring the PDL of Optical Systems or Components

As a result of rapidly accelerating demand for higher bandwidths, data center connections are migrating from 25G/100G to 400G/800G transmission speeds. Coherent receivers are expected to be able to mitigate the effects of PDL because it limits the bandwidth capacity of high-speed communication systems. Unlike other impairments that can be compensated for, such as polarization mode dispersion (PMD), PDL causes pulse distortion that cannot be…Read More

Structural Health Monitoring is Critical for Dams as America’s Infrastructure Continues to Age

The collapse of two dams in Midland County, Michigan, has created catastrophic flooding and devastation to communities along the Tittabawassee River. The Edenville Dam, constructed in 1924 and breached Tuesday, was on the Federal Energy Regulatory Commission’s list of high hazard dams, and the previous owners were warned about safety issues. Its collapse lead to flood waters rushing into Sanford Lake, causing the failure of the Sanford…Read More

Luna Joins OESH to Design and Produce Flexible 3D Printed Respirator Masks

Luna Innovations has joined forces with its Charlottesville neighbor, OESH, to design and produce flexible 3D printed respirator masks for use during the COVID-19 pandemic N95 respirator mask shortage. OESH is using its 3D printers and expertise designing around body features along with flexible, plastic material to produce the masks, which have a tight seal around the edges. The face mask can be used when…Read More

Luna’s TeraMetrix THz equipment used to examine Da Vinci’s Last Supper

 On October 21, 2019 at the request of the Museo del Cenacolo Vinciano (Milan, Italy), Polo Museale Regionale della Lombardia, Ministero per i beni e la attività culturali  and the Istituto Centrale per il Restauro (Rome, Italy), one of the most famous murals in the world, the Last Supper by Leonardo Da Vinci, was examined using terahertz (THz) and millimeter waves. Terahertz imaging is particularly…Read More
