本文将谱估计技术应用于数字全息中，对光谱反射率未知的物体进行了谱估计。在这种技术中，我们使用三个不同波长（红，绿色和蓝色）的激光器来记录物体的复振幅，并通过每个波长获得三个不同的再现图像。利用这三幅单色图像，通过光谱估计技术估计目标的连续光谱反射率信息。通过实验验证了数字全息光谱的有效性。
We applied the spectral estimation technique to digital holography to demonstrate spectral estimation of object, whose spectral reflectance has been unknown. In this technique, we use three lasers operating at different wavelengths (red, green, and blue) to record the complex amplitude of the object, and three different reconstructed images are obtained by each wavelength. These three monochrome images are used to estimate the continuous spectrum reflectance information of the object by spectral estimation technique. The effectiveness of the digital holographic spectroscopy was confirmed by an experiment.
