- 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 mu m, depth scanning range of more than 1 m, and view field larger than 70 x 70 mm(2). For depth selectivity, we set up an off-axis digital holographic imaging system using a light source with a coherence length of 400 mu m. 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. (C) 2016 Elsevier B.V. All rights reserved.
