Luna Innovations Incorporated develops, manufactures, and markets fiber optic sensing, and test and measurement products worldwide. It operates in two segments, Products and Licensing, and Technology Development. The Products and Licensing segment offers test and measurement products, which include optical vector analyzer, optical backscatter reflectometers, and the Phoenix family of tunable lasers; optical distributed sensor interrogator sensing solutions for distributed strain and temperature measurements; and Hyperion sensing solution that enable full-spectrum data acquisition and flexible peak detect algorithms of fiber-bragg grating (FBG), long period FBGs and fabry-perot sensors with low-latency access to data for closed loop feedback applications. This segment also provides general photonics comprising components, modules, and instruments to measure, manage, and control polarization and group delay in fiber optic networks; tunable lasers; and TeraMetrix products to measure and v
