An integrating sphere photometer spectral response measurement system has an integrating sphere photometer and three or more reference light sources having different peak wavelengths. The integrating sphere photometer has an integrating sphere and a broadband photodetector, wherein the broadband photodetector is mounted on a sphere wall of the integrating sphere. Emergent light of the reference light sources is incident to the integrating sphere. The total spectral radiation flux Pi(λ)(i=1, 2, . . . n) received by an integrating sphere photometer system is acquired; the response Mi(i=1, 2, . . . n) of a photometer of mixed light in the integrating sphere is read by the broadband photodetector; an equation set is established; and the spectral responsivity Srel(λ) of the integrating sphere photometer is obtained by means of numerical solution.
An integrating sphere photometer spectral response measurement method, involving an integrating sphere photometer consisting of an integrating sphere and a broadband photodetector, the broadband photodetector being mounted on a sphere wall of the integrating sphere, wherein the integrating sphere photometer is used for measuring three or more reference light sources with different peak wavelengths, wherein at least one of the three or more reference light sources is an LED light source, and the LED light source consists of monochromatic LEDs and/or white LEDs with overlapping spectra, and a spectral responsivity of the integrating sphere photometer is calculated according to a spectral radiation flux of the reference light sources and the response of the integrating sphere photometer to the reference light sources;
An integrating sphere photometer spectral response measurement system, comprising:
