OPTICAL PATH DIFFERENCE COMPENSATION MECHANISM FOR ACQUIRING TIME-SERIES SIGNAL OF TIME-SERIES CONVERSION PULSE SPECTROMETER

摘要

There is provided a time-series conversion pulse spectrometer capable of easily performing time-series conversion pulse spectrometer measurement of various samples and their states in a short time. The time-series conversion pulse spectrometer includes: a pulse laser light source; division means for dividing the pulse laser beam from the pulse laser light source into an excitation pulse laser beam and a detection pulse laser beam; detection means; a sample holding section for holding a sample; and a sample section incoming/outgoing optical system. The time-series conversion pulse spectrometer is characterized by further including: optical path length modifying means for setting at least one measurement light range arranged in the incident side optical path from the division means to the pulse light emitting means and/or the detection side optical path from the division means to the detection means; and optical delay means for measuring at least one time-series signal arranged in the incident side optical path from the division means to the pulse light emitting means and/or the detection side optical path from the division means to the detection means.
