Problems solved by technology

[0003] In the prior art, the environment of the laboratory is usually adjusted, including noise, temperature, humidity, light, etc. to provide an experimental environment for the terahertz spectrum detection equipment, but the laboratory environment is relatively complicated, and the indoor air is connected to the outside world, resulting in indoor temperature and humidity. It is not easy to control and is also affected by the background light, which seriously affects the accuracy of the experiment

Abstract

The invention discloses an auxiliary device for the experiment of terahertz spectrum detection equipment. An environment variable experiment chamber is provided for the terahertz spectrum detection equipment, the experiment chamber is formed by splicing of liquid crystal glass, the illumination in the experiment chamber is controlled by adjusting whether the liquid crystal glass is transparent ornot, the effects of fluorescence on the experiment are eliminated, the effects of external noise on the experiment are reduced, the humidity in the chamber is changed through supplying dry air or other inert gases to the experiment chamber, the temperature in the chamber is adjusted through a heater and a refrigerator, and the experiment chamber can reach an environment where the terahertz spectrum detection equipment can perform the experiment.

Description

technical field [0001] The invention relates to the field of terahertz spectrum detection, in particular to an auxiliary device used for experiments of terahertz spectrum detection equipment. Background technique [0002] Terahertz wave is an electromagnetic wave between microwave and infrared. Its frequency is in the range of 0.1THz-10THz. It has the characteristics of low energy, instantaneousness, sensitivity, and high signal-to-noise ratio. There are very important applications in detection. When the spectrometer collects the spectrum of the sample, the data measured by the terahertz spectrometer is easily disturbed by the external environment, such as irrelevant noise, temperature, humidity, and fluorescence background. In particular, the ambient temperature of its experiment needs to be adjusted to about 20°C, and the humidity adjusted to below 5%, in order to carry out normal experimental tests. Therefore, it is necessary to provide an experimental environment for t...
