Abstract

Imaging through scattering materials is of utmost importance, especially for security and biomedical imaging. Unlike the rest of the electromagnetic spectrum, terahertz radiation is a non-ionizing probe and allows imaging deep through non-conducting materials with sub-millimeter resolution. Here, we propose a coherent imaging technique reconstructing two objects, hidden one behind the other, from relative shifts between them. Experimental reconstructions at λ=96.5μm of amplitude and phase objects hidden behind a glass fabric sample are presented. The hidden objects are retrieved with a lateral resolution of 1.5λ and a depth resolution of λ/10. Besides envisioning its use in non-invasive imaging, we anticipate that, in selected applications, the suggested approach can replace a similar phase retrieval technique, namely ptychography.

Figures (4)

Fig. 1.
Fig. 1. Setup and summary of the implemented reconstruction technique. A collimated laser beam coming from the left impinges on a hidden object (here a Siemens star) and a cover object (here a schematic textile) at the distance u and with transmission functions o ( x ) and t ( x ) , respectively. The intensity of the complex wavefield Ψ j k ( x ) is recorded with a camera at multiple distances v k from the cover object. This stack of diffraction patterns allows reconstructing the complex wavefields exiting the cover object ψ j ( x ) . By shifting the cover object by the amounts x j , the two transmission functions are retrieved.
Fig. 2.
Fig. 2. Experimental reconstructions of the textile and the hidden objects (amplitude object on the left-hand side, label 1; phase object on the right-hand side, label 2). (a) Schematic of the hidden object. Reconstructed hidden object [textile] (b) [(c)] using prior information of the shifts applied to the textile, (d) [(e)] after retrieving the shifts through cross-correlation, and (f) assuming unknown shifts. (g2) Image of the textile taken with a microscope in reflection mode. The lower right panels show the colorbars used for amplitude, phase, and complex-valued reconstructions. The reconstructions of the textile share the same colorbar, where the hue encodes ϕ t and the brightness | t | . Scale bars: 1 mm.
Fig. 3.
Fig. 3. Lateral resolution of the hidden amplitude object reconstructed at multiple ( u , v 1 ) distances ( u , distance between the two objects; v 1 , textile-camera distance). The red star indicates the reconstruction distances used for the results on the left-hand side of Fig. 2 and in Fig. 4.
