WebApr 15, 2024 · This paper proposes a single-photon-counting lidar based on time coding that can obtain the target’s spatial location and measure the distance and azimuth angle in real time without needing a scanning device. Multiple optical fibers were used to introduce laser echo photons into a single-pixel single-photon detector. According to the deviation in … WebJul 5, 2024 · The spherical coordinates used in physics are x = r cos ϕ sin θ y = r sin ϕ sin θ z = r cos θ where ϕ ∈ [ 0, 2 π) is the azimuthal angle and θ ∈ [ 0, π) the polar angle. How do these relate to your angles? E.g. do you use θ ′ = π / 2 − θ for θ ′ ≥ 0 as elevation? Share Cite Follow edited May 2, 2024 at 22:22 answered Jul 5, 2024 at 6:45 mvw

In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuthal angle of its orthogonal … See more To define a spherical coordinate system, one must choose two orthogonal directions, the zenith and the azimuth reference, and an origin point in space. These choices determine a reference plane that contains … See more Just as the two-dimensional Cartesian coordinate system is useful on the plane, a two-dimensional spherical coordinate system is useful on the surface of a sphere. In this … See more It is also possible to deal with ellipsoids in Cartesian coordinates by using a modified version of the spherical coordinates.
