Method and apparatus for data processing in data modeling

The present application relates to a terahertz time-domain spectroscopy system. In this terahertz time-domain spectroscopy system, the femtosecond laser light radiated by the femtosecond laser is collimated by a first diaphragm, and then is split by a beam splitter into a pump light and a probe light. The pump light passes through the first light path module to generate a terahertz pulse, and the probe light passes through the first light path module to generate a linear polarization probe light having the same optical distance as that of the pump light. The linear polarization probe light and the terahertz pulse are combined by a beam combiner to obtain a light beam to be detected carrying the terahertz pulse information. Two electro-optical crystals with the same thickness are used in a detection device simultaneously. Changing the crystal axis angle of the two electro-optical crystals, there is a phase compensation to the two components o light and e light of the probe light, so as to realize linear detection to high power terahertz pulse and improve measurement accuracy.

The slide's movement drives the reflector placed on the slide to move together to change the optical distance of a pump light, so as to generate the delay between the pump light and a probe light.
