Title:
SPECTROSCOPIC MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/151802
Kind Code:
A1
Abstract:
A spectroscopic measurement device characterized by being provided with a light source (11) for emitting irradiation light having a wavelength range; a light splitting unit (14) for selectively allowing light from among the irradiation light having a wavelength corresponding to the value of a supplied current or voltage to pass; a light detector (17) for detecting measurement light that has passed through the light splitting unit (14) and interacted with a sample; a drive signal supply unit (18, 192) for supplying, to the light splitting unit (14), a current or voltage having a continuously varying and periodically repeating value and a modulation component superimposed thereon that varies at a period shorter than that of the value; and a synchronization detection signal generation unit (193) for generating, from the output signal output by the light detector, a synchronization detection signal having a reference frequency that is a positive integer multiple of the frequency of the modulation component.
