By using multi-spectral digital holography, it could obtain three-dimensional and spectral information from the object simultaneously. However, if the targets are dynamic objects, it is difficult to measure the spectral information by one image sensor. So, we proposed a new method that is to use a high-speed camera with burst mode and a high-speed wavelength switching light source on multi-spectral digital holography system. Then, if the speed of recording multiple holograms is much higher than object moving speed, the results will be possible as the same as the result of object in stationary state.
