In the developed multispectral imaging system the sample is illuminated diffusely by monochromatic light with an integrating sphere. The LEDs are used for monochromatic light source. The wavelengths of the 11 different type of LEDs are uniformly covering the 380–670nm wavelength range. For calibration we use gray standards placed on the wall of the sphere. The detector is a digital camera. From the multispectral image after calibration the reflectance spectra of any region can be represented.
