Abstract:
1. A composite spectral measurement method comprising: emitting a composite light from an incident light source composed of a continuous light source and a discrete light source, the continuous light source emitting wideband continuous light, the discrete light source emitting at least one single-wavelength light or at least one narrowband continuous light, wherein the wavelength of the at least one single-wavelength light or the spectrum of the narrowband continuous light is within a range of the spectrum of the wideband continuous light; using a probe, irradiating the composite light onto a target position, and receiving light reflected by the target position at the probe, wherein the wideband continuous light and the at least one single-wavelength light or at least one narrowband continuous light are irradiated onto the target position through an exiting position in the probe, and the light reflected by the target position is received at a receiving position; in a receiving unit, adding the wideband continuous light reflected by the target position and the at least one single-wavelength light or at least one narrowband continuous light reflected by the target position in an overlapped or non-overlapped manner, to obtain a composite spectrum; and in a data processing unit, analyzing the obtained composite spectrum by using a mathematical model to obtain a concentration of a component of interest.
