3.太赫兹元器件TScan-1500C-EX is designed for spectroscopic measurements in 0.1-1.5 THz frequency
range. It consists of QS2-1500-EX quasi-optical THz source and improved model of
Golay Cell detector. High output power of QS2-1050-EX and excellent sensitivity of
Golay Cells enable high resolution (1-10 MHz) and wide dynamic range (up to 100,000)
spectroscopic measurements. The basic system is configured for transmission
measurements, but it can be extended to for in reflection, Mach-Zhender or THz imaging
configurations.
Figure 1: QS2-1000 THz source, VR-3M power supply and DAU-1 unit
QS2-1500-EX THz source, shown in Figure 1, is powered by VR-3M high voltage
power supply and computer controlled via DAU-1 data acquisition unit. This source is
based on millimeter wave BWO combined with frequency multipliers. The BWO
operates at frequency range 100-180 GHz. Combination of frequency multipliers extends
the operating range to 1500 GHz.
Low noise level of TScan-1500C-EX is enabled by optimized acousto-optical detectors,
known as Golay Cells, which offer exceptionally high sensitivity. Digital signal
processing enabled by DAU-1 unit further improves detection sensitivity. Figure 2
shows typical power spectra of QS2-1500-EX and noise level of Golay Cell based
detection system.
