Setting Description
Scatter offset The distance (number of pixels) from the laser peak position to the
row where the first scatter measurement is made. The offset can
be set to 0, which means the center (reflectance) pixel is included
and that an odd number of rows is used for summing the scatter
data.
Scatter width The number of rows to sum scatter data from.
Scatter pixel format The number of bits in the scatter data.The default pixel format is
16 bits. Possible to select
Mono8 and Mono16 .
figure 50 illustrates two cases of symmetric sampling, with low scatter to the left and
high scatter to the right. The Scatter offset and Scatter width are denoted in the figure.

You can set additional scatter parameters using GenICam or GenIStream, see "GenI‐
Stream API", page 21 .
8.6.1.3 Profile meta data
Profile meta data are tagged blocks of data, that are sent together with the image data.
In Ruler3000, profile meta data are used to add additional data to the image data. The
profile meta data can only be added for 3D images. The following meta data is available
for each buffer:
• The value of the encoder counter for each line in the buffer.
• The timestamp for each line in the buffer.
• The height of the buffer.
• The width of the buffer.
• The scaling information to transform the raw data into mm (calibrated and recti‐
fied data) or pixels (uncalibrated data).
To enable profile meta data, select the Profile meta data checkbox.
8.6.2 Range (3D) measurements
8.6.2.1 Laser impact position on the sensor
The basic function of the 3D measurements is to compute the impact position of the
laser line for all columns of the selected region of interest (ROI). The light intensity
distribution from the laser line along a sensor column across the laser line can be
described as in the figure below.
