HDR mode

Knee-point

The knee-point position and the slope after the knee-point are controllable by the

Multi

slope mode (HDR)

setting. There are pre-defined parameter settings (

Off

,

PresetSoft

,

Pre‐

setMedium

, and

PresetAggressive

) that correspond to different amounts of compression.

These settings result in a dynamic range increase of approximately 2, 6, and 15,
respectively. See

In HDR mode, the sensor readout must be finished before a new exposure can start.
The sensor readout time is the time the sensor needs for the readout of the collected
data. The minimum cycle time is the sum of the exposure time and the readout time. In
linear mode, the sensor readout and a new exposure can be done in parallel.

For example: If the readout time is 33

μ

s and the exposure time is 30

μ

, the total cycle

time is 33

μ

s for linear mode and 63

μ

s for HDR, giving a maximum timed profile rate

of 30 kHz and 16 kHz respectively.

To enable HDR imaging:

1.

Open the

Multi slope mode (HDR)

to

PresetSoft

PresetAggressive

or

°

PresetSoft

increases the dynamic range by a factor ~2.

°

PresetMedium

increases the dynamic range by a factor ~6.

°

PresetAggressive

increases the dynamic range by a factor ~15.

NOTE

Using HDR affects the maximum exposure time:

•

In 2D mode, the maximum exposure time for

PresetSoft

,

PresetMedium

and

PresetAg‐

gressive

is about 16, 40 and 100 ms, respectively.

•

In 3D mode, the maximum exposure time for

PresetSoft

,

PresetMedium

and

PresetAg‐

gressive

is about 4,10 and 26 ms, respectively.
