DOI: 10.1038/s41598-024-59479-5

Abstract: Optical field imaging technology does not require a complicated optical path layout and thus reduces hardware costs. Given that only one single exposure of a single camera can obtain three-dimensional information, this paper proposes an… read more here.

DOI: 10.1109/jsen.2025.3573523

Abstract: Since thermal infrared cameras are insensitive to visual degradation caused by unknown, varying illumination, they are considered as good alternatives to the visible spectrum camera in ego-motion estimation under complex lighting conditions. However, most existing… read more here.

DOI: 10.1109/tim.2022.3160530

Abstract: Lensless fiber endoscopes allow noncontact imaging in narrow spaces without lenses or scanning devices at the distal tip. In this work, an active depth measurement module based on a Fabry–Perot interferometer is integrated onto the… read more here.

DOI: 10.3390/mi13122243

Abstract: In-process monitoring of weld penetration depth is possible with optical coherence tomography (OCT). The weld depth can be identified with OCT by statistical signal processing of the raw OCT signal and keyhole mapping. This approach… read more here.
