CALIBRATION METHOD OF SCATTERED ABSORBER MEASURING APPARATUS AND SCATTERED ABSORBER MEASURING APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a calibration method of a scattered absorber measuring apparatus which enables easier execution of measurement for calibration and the calculation of an instrument function and the scattered absorber measuring apparatus using the same. SOLUTION: As scattered absorber SM to be measured by the scattered absorber measuring apparatus, a scattered absorber for calibration with a known optical parameter is set and pulse light from a light source 20 is made incident from a light incidence position A through a light guide 40a for light incidence and the pulse light propagated scattering through the scattered absorber SM is detected by a photo detector 30 through a light guide 40b for detecting light from a light detection position B to perform a measurement for calibration. A measuring waveform obtained by a signal processing part 50 undergoes a comparison operation with a theoretical waveform by an instrument function calculating part 61 of an arithmetic processing part 60 to calculate the instrument function with a measuring apparatus itself. This facilitates the measurement for calibration and the calculation of the instrument function.
