摘要
The present invention provides a multispectral color imaging device, an automatic calibration method based on a reference reflective surface, and a method for eliminating background signals. A multispectral color imaging device including a light house module comprising a light source and a light intensity collection device surrounding the light source; an integrating sphere module including an integrating sphere, a light inlet on one side of the integrating sphere, a light outlet on the top of the integrating sphere, a sample holder gateway on the other side of the integrating sphere and a sample holder having access to the interior of the integrating sphere; and a filter wheel module including a camera, a filter wheel below the camera, and a lens below the filter wheel. The device and calibration methods of the present invention together improve the accuracy and stability of the measurement.
