DOI: 10.1080/09500340.2025.2450607
Abstract: We used the phase-stepping shearography technique to detect blind holes of various sizes and depths in a Plexiglas (PMMA or polymethyl methacrylate) plastic block. The block was strongly heated (raising the temperature by about 80C)… read more here.

DOI: 10.1109/jsen.2017.2682226
Abstract: In this paper, a new high-resolution digital imager based on a time multiplexing scheme is proposed. The imager produces a 256-grayscale image through capturing 256 successive frames that each belongs to a specific luminance range.… read more here.

DOI: 10.5194/hess-2019-34
Abstract: Abstract. Headwaters make up the majority of any given stream network, yet, they are poorly mapped. A solution to this is to model the stream networks from a high resolution digital elevation model. Selecting the… read more here.
