在彩色数字全息中，需要用一套多波长光学系统记录和再现三幅全息图。由于色差的存在，可能会发生不同波长处的不同图像的不正确叠加。我们证明，色差的补偿可以通过使用包含在多波长数字全息图的所有信息来实现。从在不同波长处重建的相位图中提取色差，从而得到完美的全色振幅重建。该方法在彩色三维全息成像和显示中具有重要的应用。
In color digital holography the recording and reconstruction of three holograms, by an optical setup operating in multi-wavelength mode, is necessary. Incorrect superposition of different images at various wavelengths may occur due to the presence of chromatic aberrations. We demonstrate that the compensation of the chromatic aberrations can be achieved by using all of the information contained in the multi-wavelength digital holograms. Chromatic aberration is extracted from phase maps reconstructed at different wavelengths, resulting in perfect full color amplitude reconstructions. The method has important applications in color 3-D holographic imaging and display.
