5.2.1. Exposure Time
The “Exposure Time” controls the Beamage-3.0’s exposure time settings. It can be set from 0.2 ms to 100
ms. The “Auto” option will automatically set the exposure time in order to have the maximum beam
intensity at 85% of the sensor’s saturation level. The exposure time can also be set manually by clicking
on the corresponding radio button and changing the value in ms.
Tip
If the beam is still saturated at a 0.2 ms exposure time, please increase
the attenuation in front of the Beamage-3.0. If the beam intensity is too
low at 100 ms exposure time, please lower the attenuation in front of the
Beamage-3.0.
5.2.2. Image Orientation
The “Image Orientation” controls rotate or flip the captured frame. The captured frame can be rotated to
90
o
, 180
o
, or 270
o
. All angles rotate clockwise. The captured frame can also be flipped horizontally or
vertically. If a frame is saved with a rotation and/or a flip, it will keep these orientation settings. Note that
the reference axis for the centroid is neither flipped nor rotated. All positions are always relative to the
image’s center which is (0,0) and the horizontal axis always increases towards the right-hand side and
the vertical axis always increases towards the top.
Warning
The image orientation is only valid on captured images. When the
Beamage-3.0 is not capturing images and is in “Animate” mode or buffer
viewing mode, it will neither flip nor rotate the current image, as it has
already been captured.
5.2.3. Image Averaging
The “Image Averaging” function is a temporal filter that captures a specified number of frames (2, 5, or
10) and averages the frames pixel by pixel to create a single time-averaged image. This lowers the total
frame rate because multiple frames need to be captured for one computation.
Tip
The Image Averaging process will smooth the beam’s fluctuations that can
occur over time. It is very useful when working with unstable laser
sources.
