Additionally, the laser scanner determines the reflectivity of the captured surfaces by measuring the
intensity of the received laser beam. In general, bright surfaces reflect a greater portion of the
emitted light than do dark surfaces. This reflectivity value is used to assign a corresponding grey
value to each single point.
The single point measurements are repeated up to 976,000 times per second. The result is a point
cloud, a three-dimensional dataset of the scanner's environment (hereinafter referred to as the
"laser scan" or "scan"). Depending on the selected resolution (points acquired per rotation) each
point cloud consists of millions of scan points.
The laser scans are recorded to the removable SD memory card, enabling easy and secure transfer
to Trimble TX5 SCENE software.

This manual provides an introduction to the TX5 3D laser scanner. At a minimum, please read Safety
Precautions and Maintenance (page 12) and Getting Started (page 32) before first use.
