Developing terahertz scanners that reveal various structural and chemical information of materials and environments through a non-invasive, non-contact platform.
Market:Terahertz technology is an emerging field with a market size of $185.98 Million. High-performance terahertz sources and detectors are much more attractive for terahertz imaging and spectroscopy applications in agricultural and pharmaceutical industries for food/drug safety monitoring. Lookin, Inc. scanners also have many other applications in auto, aerospace, construction, and oil & gas industries that need non-invasive inspection of composite materials.
Technology:Lookin, Inc. scanners employ plasmonics-enhanced terahertz sources and detectors, which greatly increase the signal-to-noise ratio (SNR) of the captured data and significantly reduce data acquisition times compared to the state-of-art. This unprecedented performance enhancement allows terahertz scanners to be used in fast and accurate chemical and structural analysis. In addition, Lookin scanners utilize an innovative algorithm to evaluate the measurement results, which solves the data-processing problems of existing terahertz systems.
