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. Lookin, Inc. develops high-performance terahertz scanners for non-destructive industrial quality control in energy, food, agriculture, pharma, oil & gas sectors.
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.
