ABSTRACT:
An optical measurement device in which changes in the output wavelength of the light source do not affect the measurement accuracy. Values representing the output wavelength of the light source are stored in a signal processing device and used to correct the measurement result for errors otherwise induced by the changes in the wavelength of the light source output.
