title: Single-shot digital holography using a spectral estimation technique.
abstract: We demonstrate a technique capable of obtaining spectral information and a three-dimensional (3D) profile of an object with a single-shot exposure. This technique is based on digital holography and the spectral estimation technique. In the demonstration of this technique, we simultaneously use three laser lines operating at 473, 532, and 633 nm to record the multiple complex amplitudes of the object corresponding to the wavelengths and obtain reconstructed monochrome images of each wavelength. A spectral estimation technique is applied to estimate the spectral reflectance of the object from the reconstructed monochrome images. We experimentally succeed in estimating the spectral reflectance of a lemon by using the technique.
