Description
Technical field
The present invention relates to a kind of sample automatic testing equipment that utilizes the terahertz time-domain spectroscopy measuring system of microprocessor controls.
Background technology
Terahertz time-domain spectroscopic technology is a kind of new technology that adopts femto-second laser to excite THz wave that gallium arsenide gives off that material etc. is surveyed.In the terahertz time-domain spectroscopy system, the acquisition of the terahertz time-domain waveform of sample is that the pump light that utilizes deferred mount to pass the different terahertz pulse electric field intensity constantly of sample through change is measured with the optical path difference of surveying light.Main source of error in experimentation has pump light, sample refraction and reflection and human factor.Pump light is subjected to the influence of fluctuations meeting of environment temperature and humidity to produce bigger amplitude and phase change; The refraction of sample and reflection are very responsive to the collimation of sample face and THz wave; It is directly related with measuring accuracy to vary the time length of article and the quality of placement sample etc.; These factors to difference constantly the repeatability of measurement data and the Terahertz wave intensity etc. that sees through sample considerable influence is arranged, produce bigger measuring error thus.
In the existing terahertz time-domain spectroscopy measurement mechanism, the most frequently used is a sample to be put into sample cell to measure at every turn.At every turn pack into about 1min of time of sample of this measuring method; Efficient is lower; The samples vertical precision of sample cell of packing into also is difficult to be guaranteed; And tend to cause that factors such as ambient humidity and temperature change in the case when packing sample into; This variation all has influence in various degree to the result of sample test; This influence can cause measurement result to exist certain distortion, even seriously influences test result.For the measurement that the minute differences sample is arranged; In order to make its effective information be unlikely to be seriously influenced; In test process, just must guarantee sample constant basically with respect to environment in the vertical precision of Terahertz light and the case, therefore traditional method of at every turn only measuring a sample is can not be adopted.
In order to address the above problem; Improve the terahertz time-domain spectroscopy efficiency of measurement; Improve the vertical precision of sample with respect to Terahertz light, the basically identical of environment in the guard box, the present invention proposes a kind of terahertz time-domain spectroscopy sample automatic testing equipment based on microcontroller.This device can be before putting into sample the water article precision of manual adjusting sample stage, thereby improve the vertical precision of sample with respect to Terahertz light.This device provides more than one sample cell, thereby can disposablely put into more than one sample, thereby has guaranteed the continuity of sample test, has reduced the change of environment in the case that brings when packing sample repeatedly into.The operation of this device after putting into sample reduced to load the shared time of sample repeatedly, thereby improved the efficient of sample test almost all by microprocessor controls.In addition; This terahertz time-domain spectroscopy sample automatic testing equipment based on microcontroller also provides initial position self-adjusting zeroing function; The liquid crystal display circuit that this device adopts can be real-time current system running status and when the sample cell numbering of Pretesting; Mistake such as reduced the omission that the artificial memory brings, obscure, the raising of maximum possible measuring reliability.
Though the similar sample rack device is also arranged at present; But present device difficult guarantees the vertical precision of sample with respect to Terahertz light; And after putting into sample, can not regulate the initial position of specimen holder automatically; There is not corresponding display device; Need the artificial current sample cell numbering of going to remember; Also do not have control circuits such as corresponding button input, it is very inconvenient to operate, and measuring accuracy is difficult to guarantee.Along with the increase of experiment number and put into the sample number and increase, use existing apparatus to be easy to cause the omission of sample test step and obscure, be difficult to guarantee the reliability of sample test.
