Non-destructive testing of graphene/epoxy composites using THz waves
(2018-10-05)
In earlier experiments [1] we found there was significant transmission of THz radiation through carbon-fiber enforced composites, despite that fact that the dc conductivity of the carbon fibers is expected to be good and ...
Identification of mixed substances using a random forest regressor to classify THz absorbance spectra
(2018)
We report on the development and application of a random forest regressor that not only identifies but also estimates the relative concentrations of substances (one explosive and two simulants), both in one-substance and ...
Eye-safe fiber laser for long range 3D imaging applications
(2018)
We report an all-fiber Er/Yb master oscillator power amplifier at 1.55 μm, delivering 135 μJ pulses with 6 ns duration (full width at half-maximum) at 100 kHz pulse repetition frequency, limited by stimulated Brillouin ...
