Detection and analysis of the chemical substance and the biological substance which are by the passive emission of the terahertz wave for the low temperature background target

摘要

The sample (12) the device which it detects and analyzes the chemical substance and the biological substance in and (38). The device (38), in order to detect the substance in the sample, the sample of the terahertz band (12) from the spectrometer which receives the emission passively (42) it includes. The telescope (46) or the other device is used, although the spectrometer (42) range of vision is restricted. The low temperature surface (16), in order the spectrometer (42) with on opposite side, the spectrometer (42) to bury range of vision the sample (12) vis-a-vis, it is arranged. The low temperature surface (16), bringing the low temperature background the sample (12) vis-a-vis, it decreases the background emission, the sample (12) from improves the detection of the emission.
