Amplitude Characteristics

In addition to the measured value output for the distance, the R2000 provides an
echo amplitude for each measuring step. The measured value for the echo
amplitude is a value with no unit of measurement in a range from 0...4095 digits.
The echo amplitude is a measure of the energy received by the R2000. The
measured value is dependent on the surface properties of the measurement
object (reflectivity, structure), the distance from the measurement object, and the
angle of incidence of the measurement beam. The measurement of the echo
amplitude is not calibrated and is used for relative distinction between different
object reflectivities.
In particular, evaluation of the echo amplitudes can be used to distinguish
between natural surfaces and reflector film.
The picture below shows the curve of the echo amplitude on reflector film
(diamond grade 983-10). The curve represents the smallest expected measured
value in relation to the distance.
The second curve represents the largest value on white (90 % reflectivity), natural
surfaces in relation to the distance.
