Scan pattern
The scan pattern consists of vertically arranged, individual scan lines. Their angular spacing or
distribution is calculated by dividing the vertical FoV by the number of scan lines. For example,
a vertical FoV of 30° and 100 scan lines yield a vertical resolution of 0.3°.
The frame rate also depends on the number of scan lines. It describes how often the total scene
is scanned per second. The installed beam deflection unit permits a scan rate of 500 scan
lines/s. In the above example, this results in a frame rate of 500/100 1/s = 5 Hz. “Fig. 5 Scan
pattern” on page 14 illustrates the relationship between the number of scan lines and the
frame rate.
The straight edges that limit the horizontal FoV on both sides are intended to protect the eyes.
Another possible setting is the horizontal resolution, which describes the spacing between
two laser pulses along a scan line in the angular range, see “3.1.3 Function description” on
page 11.

The figure shows scan patterns with different numbers of scan lines. The more scan lines are
configured, the longer it takes to measure a complete image.
