Description
Our new all-fiber THz spectrometer for fast data aquisition is based on the novel OSCAT (Optical Sampling by CAvity Tuning) technique. It enables THz time-domain spectroscopy without any moving parts. Combined with our TERA Image extension, the system provides a solution for fast THz imaging applications. Similar to the ASOPS technique, the OSCAT offers great flexibility in system configuration and capability of high-speed measurements. TERA OSCAT is a robust and portable solution for both laboratory use and OEM integration, suitable even for harsh industrial environment.
System layout:
Principle of operation:
In the OSCAT technique there is no need for an external moveable delay line. Contrary to the conventional THz-TDS systems, the lengths of the emitter and detector arms are not balanced. The temporal shift Dt between the pulses i (emitter arm) and i+a (detector arm) is determined by the repetition rate frep of the fs laser.
