Claim Text:
1. A spectroscopic measurement device comprising: a first substrate; a second substrate opposed to the first substrate; a first reflecting film provided to the first substrate; a second reflecting film provided to the second substrate, and opposed to the first reflecting film across a predetermined gap; a gap amount changing section adapted to change the gap amount of the gap by deflecting the second substrate by applying a continuously varying analog voltage; a detection section adapted to detect a light intensity of light interfered between the first reflecting film and the second reflecting film; a filter drive section adapted to apply the continuously varying analog voltage to the gap amount changing section; a voltage monitoring section adapted to monitor the continuously varying analog voltage applied to the gap amount changing section; a storage section adapted to store V-λ data corresponding to a relationship between the continuously varying analog voltage applied to the gap amount changing section and a wavelength of the light taken out by the first reflecting film and the second reflecting film; and a light intensity acquisition section adapted to obtain the light intensity detected by the detection section at a timing at which the light taken out by the first reflecting film and the second reflecting film has a measurement target wavelength based on the continuously varying analog voltage monitored by the voltage monitoring section.
