Abstract
We simultaneously capture holograms using multiple wavelengths with a single camera using off-axis holography. Our prototype uses two tunable lasers and the references or local oscillators are configured so that the reconstructed complex signal field at each wavelength fills different quadrants. The technique can be adapted for various applications and could be especially beneficial for 3D reconstruction of moving objects and high resolution imaging.
