Abstract:
1. A measurement apparatus for measuring a measurement object, the measurement apparatus comprising: a waveform acquiring device configured to acquire a time waveform of an electromagnetic wave from the measurement object by time-domain spectroscopy; and a processing device configured to process the time waveform of the electromagnetic wave, wherein the processing device includes: a transforming unit configured to transform the time waveform of the electromagnetic wave into wavelet expansion coefficients by wavelet transform; a weighting unit configured to weight each of the wavelet expansion coefficients; and an inverse transforming unit configured to inverse transform the weighted wavelet expansion coefficients into a time waveform by inverse wavelet transform, wherein the measurement object has an absorption spectrum, and wherein the weighting unit weights each of the wavelet expansion coefficients based on a level of correlation between the wavelet expansion coefficient and the absorption spectrum.
