Infrared thermal-wave detecting system for vacuum low-temperature environment

Abstract

The invention discloses an infrared thermal-wave detecting system for a vacuum low-temperature environment. The infrared thermal-wave detecting system comprises an internal infrared detecting part, external measuring equipment and power supply equipment, wherein the internal infrared detecting part can be arranged in the vacuum low-temperature environment; the external measuring equipment and the power supply equipment are connected by a network data transmission cable and are arranged outside the vacuum low-temperature environment; the internal infrared detecting part comprises a thermal control cabin, an infrared thermal imager and a cloud platform; the infrared thermal imager is arranged in the thermal control cabin in a sealed manner, and the lower part of the infrared thermal imager is supported on the rotatable cloud platform penetrating through the bottom part of the cloud platform; the cloud platform is coated with heating fins for transferring heat for the infrared thermal imager and a plurality of layers of insulating materials; germanium glass is arranged in a position of the thermal control cabin, which is right opposite to a lens of the infrared thermal imager, so as to receive infrared rays of the vacuum low-temperature environment and carry out temperature measurement, and the measurement result is in electric communication with external measuring equipment by the network data transmission cable. The infrared thermal-wave detecting system has the advantages that not only is the problem of non-contact temperature measurement in a vacuum container solved, but also the reasonable thermal control design ensures working safety of the system in the low-temperature environment.

Description

technical field [0001] The invention belongs to the field of thermal imaging, and in particular relates to an infrared detection system suitable for a vacuum and low temperature environment. Background technique [0002] Infrared thermal wave detection is an important technology in the field of non-contact measurement, which plays an important role in non-contact temperature measurement and thermal imaging.
