Laser source
In the Cube, the laser source is a collimated laser diode with a wavelength of 905 nm. The
emitted laser source has a collimation of 0.4° for Cube 1 and 0.24° for Cube Range 1. The laser
is actuated in such a way that a regular pattern results in the point cloud with the set horizon-
tal resolution. The pulse energy is adapted dynamically for the horizontal angular resolution on
the basis of the laser class 1 limitation described in IEC 60825-1:2014. As a result, the achievable
range of the Cube drops when the angular resolution is finer.

Field-of-view
The Cube sequentially scans the surroundings using two scanners in the form of MEMS mir-
rors. They deflect the laser beam horizontally and vertically to measure a scene in two dimen-
sions. The sum of the maximum deflection angles is called the field-of-view (FoV). If a scanner
deflects the laser by +/- 35°, for example, this corresponds to an FoV of 70°.
One of the scanners swivels with a constant amplitude thus generates the horizontal FoV (see
“3.3.6 Technical specifications” on page 17). The second scanner, which is responsible for
the vertical deflection, changes its amplitude continuously so that the entire vertical field-of-
view of the Cube is scanned and measured. The resulting scan pattern is similar to an ellipse
(see “Fig. 4 Field-of-view” on page 13) whose vertical size changes. The opening and closing
process repeats at the frame rate. One complete scan of the scene is called a frame.
