This paper describes a digital method that is capable of automatically focusing optical coherence tomography (OCT) en face images without prior knowledge of the point spread function of the imaging system. The method utilizes a scalar diffraction model to simulate wave propagation from out-of-focus scatter to the focal plane, from which the propagation distance between the out-of-focus plane an...

This paper focuses on the sampling problem in light field rendering (LFR) that is a fundamental approach to image based rendering. Quality of LFR depends on a light ray database generated from pre-acquired images, since image synthesis is a process of gathering appropriate light ray data from the database. For improving the quality, interpolation of light ray data is effective. It is based on a...

An upgraded and improved version of the Focal Plane Detector (FPD) large-acceptance magnetic spectrometer MAGNEX is described here. The FPD consists a tracker operating at low pressure silicon detector wall. Thanks to different geometry electron multiplication induction elements, new guarantees superior signal noise ratio, resulting in more accurate tracking cleaner identification detected heav...

The photonic lantern (PL) is a tapered waveguide that can efficiently couple light into multiple single-mode optical fibers. Such devices are currently being considered for number of tasks, including the coupling telescopes and high-resolution, fiber-fed spectrometers, coherent detection, nulling interferometry, vortex-fiber nulling. In conjunction with these use cases, PLs simultaneously perfo...
