Abstract :
A fast and reliable novel technique for a terahertz liquid spectroscopy based on the double-modulated differential time-domain spectroscopy (Double-modulated DTDS) is presented. This technique is implemented using a robust stainless-steel wheel with a dual-thickness cyclic olefin copolymer (COC) window driven by a high speed brushless 3 phase motor.
