Title:
LASER RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/138766
Kind Code:
A1
Abstract:
Provided is a laser radar device comprising: a frequency shift correction unit (25) for correcting the shift of the frequencies of a plurality of first signal spectra in the same time range with respect to the frequency of first laser light, and correcting the shift of the frequencies of a plurality of second signal spectra in the same time range with respect to the frequency of second laser light; and a spectrum integration unit (26) for integrating the plurality of first signal spectra corrected by the frequency shift correction unit (25), and integrating the plurality of second signal spectra corrected by the frequency shift correction unit (25). A molecular concentration calculation unit (27) calculates the concentration of molecules in the atmosphere, from the first and second signal spectra integrated by the spectrum integration unit (26).
