Abstract

Fast frequency sweep mode is a promising method for spectrum recording in a sufficiently wide frequency range within a short time (about a few milliseconds). This approach permits one to detect all substances which have intense absorption lines lying in the frequency range of the spectrometer and which are in a gas mixture when the spectrum is recorded. A spectroscopic system consisting of spectrometers for the centimeter and two-millimeter wavelength ranges operating in fast frequency sweep mode is presented. The possibility of creating a radiation source with fast frequency sweep based on a quantum cascade laser of the terahertz frequency range is explored. The results of numerical simulation for such a source based on experimental characteristics of the studied quantum cascade laser are given. The possibility of using these spectrometers to examine the composition of a mixture of vapors and thermal decomposition products of the tissues of ENT organs is shown.

在太赫兹频率范围内采用快速扫频模式实现非平稳气体光谱方法的可能性

快速扫频方式是在短时间内(约几毫秒)在足够宽的频率范围内记录频谱的一种有前途的方法。这种方法允许人们检测在光谱仪的频率范围内具有强吸收线的所有物质，并且在记录光谱时处于气体混合物中。提出了一种由厘米和二毫米波长范围的光谱仪组成的快速扫频光谱系统。探讨了利用太赫兹量子级联激光器制造快速扫频辐射源的可能性。根据所研究的量子级联激光器的实验特性，给出了该源的数值模拟结果。显示了使用这些光谱仪检查耳鼻喉器官组织的蒸汽和热分解产物混合物的组成的可能性。
