摘要
Interference noise is eliminated and fitting accuracy is enhanced.;A spectrum analysis apparatus includes an electromagnetic wave source configured to emit an electromagnetic wave having a wavelength from 0.1 mm to 10 mm, a spectrometer a detecting section configured to detect an emitted electromagnetic wave that exits from the measurement object, the wave being transmitted through or reflected by the measurement object, and to generate a detection signal; and an analyzing section configured to analyze the detection signal. The analyzing section has a noise eliminating unit configured to generate a noise eliminated signal by eliminating from the detection signal a round-trip electromagnetic wave having reciprocated twice or more inside the measurement object and then emitted from the measurement object, in the emitted electromagnetic wave. Furthermore, the analyzing section is configured to generate a transmission or reflection spectrum that is a corrected detection signal by using the noise eliminated signal.
