Abstract

Imaging systems targeting macroscopic objects tend to have poor depth selectivity. In this Letter, we present a 3D imaging system featuring a depth resolution of 200 μm, depth scanning range of more than 1 m, and view field larger than 70×70 mm². For depth selectivity, we set up an off-axis digital holographic imaging system using a light source with a coherence length of 400 μm. A prism pair was installed in the reference beam path for long-range depth scanning. We performed imaging macroscopic targets with multiple different layers and also demonstrated imaging targets hidden behind a scattering layer.
