The range finder electronics of the 3D laser scanner RIEGL VZ-400 is optimized
in order to meet the requirements of high speed scanning (fast laser pulse repetition
rate, fast and highly accurate digital signal processing, and versatile interfacing).
The vertical deflection ("line scan") of the laser beam (1) is
realized by a polygonal mirror (2) with a number of reflective
surfaces.
|
|
For high scanning rates and/or a vertical scan angle (theta) up to 100°, the
polygonal mirror rotates continuously at adjustable speed. For slow scanning rates
and/or small scanning angles, it oscillates up and down. The limitless 360°
horizontal scan ("frame scan") is provided by rotating the complete optical
head (3).
Scandata, consisting of RANGE, ANGLE, SIGNAL AMPLITUDE, and optional TIMESTAMP is
stored locally or on a USB storage device (8) attached to
the instrument or transmitted to a laptop (10) via TCP/IP Ethernet
Interface (6). The camera (9) is controlled by the
instrument and the picture data is stored or transmitted together with the scan
data.

RIEGL VZ-400
The V-Line 3D Terrestrial Laser Scanner RIEGL VZ-400 provides high
speed, non-contact data acquisition using a narrow infrared laser beam and a fast
scanning mechanism.
High-accuracy laser ranging is based upon RIEGL’s unique echo digitization
and online waveform processing, which allows achieving superior measurement capability
even under adverse atmospheric conditions and the evaluation of multiple target
echoes. The line scanning mechanism is based upon a fast rotating multi-facet polygonal
mirror, which provides fully linear, unidirectional and parallel scan lines.

The RIEGL VZ-400 is a very compact and lightweight surveying instrument,
mountable in any orientation and even under limited space conditions.
