[0041]Before the test starts, the operator first determines the test form according to the sample to be tested, then pulls the handle 11 to open the front cover 12, and then the adjusting nut 14 can be seen, loosen the adjusting nut 14, and rotate the transmitting probe 5 and receiving probe 15 to the desired position. After the desired angular position, tighten the adjusting nut 14, and then close the front cover 12. Then loosen the locking screw 6 of the upper flip cover 4, flip up and open the upper flip cover 4, and place the sample 10 to be tested on the storage table. Special samples can use special fixtures, and the placement method is not limited. After the tested sample 10 is placed, close the flip cover 4, and tighten the locking screw 6. At this time, the replacement of the internal gas filling can be performed through the air intake hole and the exhaust hole. In this process, it can be determined whether the internal gas filling is completed by observing the parame...

Abstract

The invention discloses a terahertz time-domain spectral analysis room. The terahertz time-domain spectral analysis room comprises a shell of the analysis room composed of a bottom plate, an outer frame, a front vertical plate and an upper turning cover, a displacement table is arranged at the position, located on the bottom plate, in the analysis room, and a shelving table is arranged on the displacement table. One ends of a transmitting probe bracket and a receiving probe bracket, located on the front vertical plate, are hinged in the analysis room, a transmitting probe is fixed to the otherend of the transmitting probe bracket, a receiving probe is fixed to the other end of the receiving probe bracket, the transmitting probe and the receiving probe are correspondingly located on the two sides of the shelving table, a round of arc-shaped grooves are formed in the position, located on the periphery of hinged points, on the front vertical plate, and rotary handles of the transmittingprobe bracket and the receiving probe bracket penetrate through the arc-shaped grooves and are in screw joint with adjusting screw nuts. According to the terahertz time-domain spectral analysis room,the testing requirements of all tested samples can be met, horizontal transmission, vertical transmission and reflection test with all angles can be realized, the positions of the samples are automatically adjusted, and the internal temperature and humidity and pressure state of the analysis room are observed at any time.

Description

technical field [0001] The invention relates to a spectrum analysis room, in particular to a terahertz time-domain spectrum analysis room. Background technique [0002] Terahertz time-domain spectroscopy technology is the latest electromagnetic spectrum technology, which has important application prospects in many basic research fields, industrial application fields, medical fields, military fields and biological fields. Terahertz spectroscopy technology not only has a high signal-to-noise ratio, but can quickly analyze and identify subtle changes in sample composition, and this technology is a non-contact measurement technology that can quickly and accurately measure the physical information of semiconductors, dielectric films and object materials . [0003] Terahertz time-domain spectroscopy can be divided into transmission type, reflection type, differential type and ellipsometry, among which transmission type and reflection type are the most commonly used. [0004] Sin...
