  The development of single-photon counting detectors and arrays has made
tremendous steps in recent years, not the least because of various new
applications in, e.g., LIDAR devices. In this work, a 3D imaging device based
on real thermal light intensity interferometry is presented. By using gated
SPAD technology, a basic 3D scene is imaged in reasonable measurement time.
Compared to conventional approaches, the proposed synchronized photon counting
allows using more light modes to enhance 3D ranging performance. Advantages
like robustness to atmospheric scattering or autonomy by exploiting external
light sources can make this ranging approach interesting for future
applications.
