Abstract: To provide a light source apparatus for light measurement in which time wavelength uniqueness is not lost even in a case of high output, and to enable spectroscopic measurement with high accuracy and at high speed. Broadband pulsed light having a continuous spectrum over a wavelength width of at least 50 nm in a range of 900 to 1300 nm is emitted from a pulsed light source, and divided for each wavelength by a divider, and light having each wavelength is transmitted by each of stretch fibers and emitted from a coupler. The stretch fibers have different lengths such that an elapsed time and the wavelength in one pulse correspond to each other on a one-to-one basis at an emission end.

Abstract: In a Fourier-transform spectroscopy apparatus, a scanning mirror is arranged on a light path of scanning light. The scanning mirror delays or advances the scanning light with respect to reference light according to the rotational angle of the scanning mirror from its initial position. A spectroscopic spectrum generating unit generates an interferogram based on the intensity of the detection target light obtained from the detection target, and Fourier transforms the interferogram thus generated. The spectroscopic spectrum generating unit corrects the nonlinearity of the group delay between an envelope of the reference light and an envelope of the scanning light, and corrects the nonlinearity of the phase shift between the respective envelopes.

Abstract: A color measurement instrument for measuring colors of areas of interest of a target object includes a spectral engine, a color camera, a display, and a processor. The spectral engine has a first field of view. The camera has a second field of view, the second field of view being larger than the first field of view and encompassing the first field of view. The processor is coupled to the spectral engine, camera and display, and configured with instructions that, when executed, cause the processor to display a live view of the second field of view on the display with a representation of the location of the first field of view superimposed on the displayed live view, an area of interest is detected as wholly occupying the first field of view, and a measurement is made.
