Title: LIGHT ABSORPTION MEASURING DEVICE FOR ABSORPTION SPECTROMETRY, AND ABSORPTION SPECTROMETRY SYSTEM EMPLOYING SAME
Abstract:
In order to achieve a light absorption measuring device for absorption spectrometry with which it is possible to monitor the condition of a substance in a minute space at high speed and with high precision on the basis of laser absorption spectrometry, a light absorption measuring device (B) for absorption spectrometry is configured from: a transmission/reception integrated fiber probe (1); a light emitting/receiving mechanism (2) which radiates light from the probe distal end (1x), receives a plurality of beams of reflected light that have been transmitted through a substance to be measured and have returned to the probe and that have different phases, and converts the same into electrical detected signals (Sa) to (Sf); a lock-in amplifier (3) which extracts signals corresponding to absorption of light of a specific wavelength, using the detected signals (Sa) to (Sf) as signals for extraction; and a combining unit (4) which is disposed downstream of the lock-in amplifier (3) and which combines the extracted signals (Sa) to (Sf) together.
