The advantages of this technique are that it is continuously tunable over the frequency range from 300 GHz to 3 THz (10 cm−1 to 100 cm−1) (1 mm to 0.1 mm), and spectral resolutions in the order of 1 MHz can be achieved.
The benefits of this technique are that it is continuously adjustable across the frequency spectrum from 300 GHz to 3 THz (10 cm−1 to 100 cm−1) (1 mm to 0.1 mm), and spectral resolutions in the range of 1 MHz can be attained.
