Exposure time

Once the height of the sensor region is set, there are two other settings that affect the
profile rate of the camera:

Exposure time (

μ

s)

The time (

μ

s) during which the sensor region is exposed.

This controls the duration where the photosensitive cells are
exposed to light.

Timed profile rate (Hz)

The rate at which the profiles in an image are captured (Hz).
Only applicable when the camera is in free-running mode.
(The 

Timed profile rate

 is defined in the 

Profile triggering

 section.)

The exposure time and the profile rate are inter-dependent. The maximum exposure
time cannot be longer than the time between two profiles, minus about three microsec‐
onds that are needed for readout and reset.

You can see the maximum profile rate possible for the current configuration by clicking
on the 

Timed profile rate

 field. The maximum profile rate is shown in the information field

at the bottom.

NOTE

The maximum exposure time and the maximum profile rate are stored as floating-point
values and rounding-off effects may make it impossible to set the exact value returned
by the GUI. The maximum deviation is 0.01 

μ

s for the exposure time and 0.01 Hz for

the line rate.

Setting exposure time

Tab: 

2D Image

1.

Look at the 2D image and the laser line and adjust the 

Exposure time

 parameter

until the laser line is imaged as a narrow bright stripe and the background is not
visible, see the figure in the middle below. The laser line should be approximately
4 to 8 pixels wide.

Figure 32: Too short exposure time: Laser line hardly visible.

Figure  33:  Normal  exposure  time:  Laser  line  bright  but  not  saturated.  No  background
visible.
