| Abstract: | The possibility of frequency-resolved imaging using terahertz emission from laser filament plasma is demonstrated in the range from 1 to 10 THz. By leveraging axisymmetric terahertz emission from a DC-biased filament, the spatial and spectral properties of a multi-component object are characterized. Therefore, laser filament terahertz emission can be applied for spectroscopic imaging of objects. [ABSTRACT FROM AUTHOR] |
