Non-line-of-sight (NLOS) imaging enables monitoring around corners and is promising for diverse applications. The resolution of transient NLOS limited to a centimeter scale, mainly by the temporal detectors. Here, we construct an up-conversion single-photon detector with high ~1.4 ps low noise count rate 5 counts per second (cps). Notably, operates at room temperature, near-infrared wavelength....
Abstract In this work, we study a new model for continuum line-of-sight percolation in random environment driven by the Poisson–Voronoi tessellation d -dimensional Euclidean space. The edges (one-dimensional facets, or simply 1-facets) of are support Cox point process, while vertices (zero-dimensional facets 0-facets) Bernoulli process. Taking superposition Z these two processes, points linked ...
We describe the results of a detailed study of the polarization properties of the broad Hα line in Type 1 Seyfert nuclei. Our analysis of these data points to a model in which the broad Balmer lines are emitted by a rotating disk, and are scattered in two main regions – one co-planar with the disk and within the circum-nuclear torus, the other, the polar scattering region, outside the torus but...
The line of sight (LOS) rate is a parameter that is needed to calculate the acceleration applied to missiles by the proportional guidance laws in order to hit the target. This rate is usually measured using gimbaled seekers. However, if the type of missile seeker be strap down, the LOS rate must be calculated from deriving the missile's seeker output angles or estimation methodes. The derivatio...
