5.5.4.9 Unit
The measurement units that are displayed in the Beam Software can be selected in the Unit
topic.
Position units: µm or pixel .
Total Power units: mW or dBm .
Temperature: °C , °F or K .
(Temperature is measured inside the camera.)
The following table gives an overview on all available units:
Unit Description
pix Location, width or distance, related to the image sensor pixels. The origin of the co-
ordinate system (X=0, Y=0) is the sensor center, not the image center!
Positive X values go to the right, positive Y values to the top of the image.
µm Location, width or distance in µm, calculated from the camera pixels. 1 pixel = 6.45
µm.
The origin of the coordinate system (X=0, Y=0) is the sensor center, not the image
center!
Positive X values go to the right, positive Y values to the top of the image.
mW The Total Power of the beam is calculated from the integral intensity of the image
using the wavelength dependent sensor response, the Exposure Time and Gain of
the camera as well as the filter attenuation and the power correction value.
dBm The Total Power translated from mW into dBm: 10 * log (P[mW]), 0 dBm refers to 1
mW.
% Relative level between 0 and 100%.
deg Angle in degree with respect to the X axis, range -90° to +90°.
5.5.5 Plot Over Time Parameter
The Beam Software allows to show different plots of beam measurements:
Plot Positions
Plot Power
Plot Diameters
Plot Gaussian Fit
Plot Orientation
Plot Environment Data
Beam Stability
The section Plot Over Time Parameter is used to configure these plots:
