With increasing distance from the LMS5xx, the distance between the individual measured
points also increases. The distance between the measured points is also dependent on the
angular resolution selected. With a coarser resolution (e.g. 1°), the distance is larger, with
a finer resolution (e.g. 0.1667°) the distance is smaller. The distance-dependent spacing
between the measured points is the tangent of the angular resolution × distance.
Fig. 14: Schematic layout of the distance between measured points at different angular
resolutions
The diagram in Fig. 15 shows the beam diameter and the measured point spacing as a
function of the distance from the LMS5xx.
Important Full scanning without gaps depends on the resolution of sensor (SR or HR) and the
selected angular resolution.

Example for angular resolution 0.1667° (HR) in Fig. 15
Distance intersection point 30 m gives a distance between the measured points of approx.
87 mm.
Distance intersection point 30 m with the characteristic curve for beam diameter gives a
beam size of approx. 150 mm (HR) or 342 mm (SR).
