Patent number: 10408679Abstract: 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.Type: GrantFiled: August 4, 2016Date of Patent: September 10, 2019Assignees: Shenzhen Institute of Terahertz Technology and Innovation, Shenzhen Terahertz System Equipment Co., LTD.Inventors: Shichang Peng, Yi Pan, Chen Li, Qing Ding

Patent number: 10161790Abstract: A delay line device and a terahertz time-domain spectrometer system include: a baseplate, a slide rail component, in which the slide rail component includes a slide, a reflector, a grating ruler component, and an electric-magnetic induction component. When the electric-magnetic component, after being applied a current, cuts the magnetic induction coil to generate power to push the slide moving, the grating ruler component placed on the slide rail component collects the movement information of the slide. 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.Type: GrantFiled: August 10, 2017Date of Patent: December 25, 2018Assignees: Shenzhen Institute of Terahertz Technology and Innovation, Shenzhen Terahertz System Equipment Co., Ltd.Inventors: Qing Ding, Shichang Peng, Yi Pan, Chen Li
