| titleOfInvention | Infrared radiometer applied in vacuum low-temperature environment and measuring method |
| abstract | The invention discloses an infrared radiometer applied in a vacuum low-temperature environment, which comprises an external calibration source, an optical system, an internal calibration source, a modulation fan, an infrared detector assembly, a preposed broadband amplifier, a phase-locked amplifier and a data acquisition, processing and controller. The internal standard source and the external standard source are used for calibrating the infrared radiometer; the optical system is used for collecting target light; the modulation fan is arranged between the optical system and the infrared detector assembly, modulates the detected light radiation and serves as the synchronous input of the phase-locked amplifier; the preamplifier amplifies the output signal of the infrared detector component and outputs the amplified signal to the lock-in amplifier, the lock-in amplifier processes the amplified signal to form a signal which is in direct proportion to the infrared radiation value of the measured target, the signal is acquired by AD, and the signal is processed by a computer and software to form a measuring result. The invention can realize on-orbit multipoint, high-precision, wide temperature range, quick magnitude traceability or radiation magnitude measurement of the calibration source for on-orbit calibration. |
