Single-shot 3D endoscopic imaging exploiting a diffuser and neural networks [PDF]
EPJ Web of Conferences, 2022 Lens-based endoscopes offer high lateral resolution, but suffer from rigid imaging properties, such as a fixed focal plane. We present a miniaturized 0.5 mm diameter endoscope in which the objective lens is replaced by an optical diffuser.

A novel high accuracy 3D scanning device for rock-art sites [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014 We are currently developing a novel 3D scanning device for rock-art. Within the European project 3D-Pitoti, this scanner shall be used to acquire 3D structure and radiometric surface properties of ancient rock-art sites in Valcamonica.

The measure of a measurement [PDF]
Journal of Mathematical Physics, 2007 We identify a fractal scale s in a family of Borel probability measures μ on the unit interval which arises independently in quantum information theory and in wavelet analysis. The scales s we find satisfy s∊R+ and s≠1, some s<1 and some s>1.
