Introduction to off-axis digital holography. A technique for reconstructing the spatial amplitude and phase of an optical field, by measuring the resulting intensity of the interference between the field and a tilted plane-wave (which serves as the phase reference). • 0:00 Introduction • 5:08 Comparison to traditional analog holography • 6:20 Implementation details • 6:57 Coherence requirements • 10:56 Lossy vs. lossless implementation • 13:42 Step-by-step. Fourier processing the interferogram (digital hologram) • 19:15 Removing the Reference wave from the final reconstructed field. • 21:55 Spatial/angular resolution requirements and limitations. • Bonus animation of the effect of the finite detector area of the camera pixels and using Reference wave aliasing whereby the Reference wave is at a steeper angle than the camera pixels can resolve. • • Off-axis digital holography (Referenc...
