Working with Reflections (continued)
Extended Reflection Data
The Reflection Pulses pane contains details about the number of pulses that make up each
reflection, and their angle of incidence.
Pulse - This column displays the number of laser pulses that have been received back
from each target.
In general, the larger the target the more pulses that will be returned.
This value will increase as the distance to the target reduces.
Width
- The Width column shows the horizontal width of each target, measured in
degrees.
Lower, Middle and Upper - These columns indicate whether
the scanner is pointing low or high in relation to the detected reflections.
This can occur when the CyScan vessel is working close to a rig and the targets are
mounted high above the scanner (see
Manually Tilting the Scanner
on page 26).
Rev #
- The total number of revolutions made by the scanner rotor since CyScan was last
powered up or resumed.
Pulses - The total number of laser pulse returns received during the last revolution of the
scanner rotor.
Temperature - The temperature inside the scanner unit (see
Low Temperature
Operation
on page 53).
