Abstract

High-speed Terahertz Time domain spectroscopy (High-speed THz-TDS) system is developed on the basis of traditional THz-TDS. It can effectively compensate for the shortcomings of traditional THz-TDS. High-speed THZ-TDS features fast spectrum scanning speed and High spectrum resolution. But it needs a stable local clock signal to lock the repetition rate of the laser in the system. In this paper, a method of taming OCXO with China's BeiDou Navigation Satellite System (BDS) is proposed to generate stable clock signals. Using this signal as the local clock for the high-speed THZ-TDS. The cost of this method is 2,600 yuan, less than one-tenth of the price of rubidium atomic clocks, without significantly reducing stability. This method provides a high stability, low cost clock signal for high-speed THZ-TDS system, and has long term stability.
