Received Light Waveform and Measurements
The heights of all the parts where the laser strikes the target are measured
from the waveform. The waveform is a vertical graph of the reflected light
of the laser.
The following two settings are related to the recognition of the received
light waveform. Normally you do not have to change these settings.
Threshold
If the amount of light of a part of the received light waveform is less than
or equal to this setting value, that part of the waveform triggers alarm (no
measured value).
The unit is the received light amount (in 256 levels).
If you specify a value that is too high, the number of areas where
measurement is not possible will increase.
If you specify a value that is too low, noise components will also be measured,
which may lead to unstable measurements.
[1] The peak of the received light waveform
is greater than or equal to the light
amount threshold.
[2] The peak of the received light waveform
is less than the light amount threshold.
Light amount threshold
Measurement is possible.
