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...
We found out a problem that the non-diffraction wave was not completely removed in parallel phase-shifting digital holography (PPSDH) system using a polarization imaging camera. To solve this problem, we introduce an algorithm for compensating the reconstructed image, which can remove the residual non-diffraction wave. In the algorithm, the phase-shifted holograms generated by image reconstruction...
Parallel phase-shifting digital holography has attractive features in the instantaneous measurement of three-dimensional field with better spatial resolution compared with off-axis digital holography. It is important to evaluate the recording property of parallel phase-shifting digital holography for fast three-dimensional events. In this paper, we review the photon counting approach to assess the...
