Camera Performance and Features
When selecting TDI Area mode, the Device Scan Type changes to Area scan and the height feature
changes to 128, automatically.
Internal Trigger Mode
See the section Camera Control Category in Appendix A for GenICam features associated with this
section and how to use them
Related Feature: AcquisitionFrameRate, AcquisitionLineRate
In the different TDI Modes use the following features to set the internal trigger rate:
TDI Mode Trigger Rate Feature Maximum
TDI AcquisitionLineRate 300 kHz
HDR / HFW AcquisitionLineRate 150 kHz
Area AcquisitionFrameRate 2 kHz
TDI Stage Selections
See the section Camera Control Category in Appendix A for GenICam features associated with this
section and how to use them
Relevant Features: sensorTDIStagesSelection
When operating in different TDI modes the number of stages in the array is adjusted, resulting in
different responsivities.
In TDI mode, the main array is configurable to 128 or 64 stages. The second array is not used.
In HDR and HFW modes, the number of stages is selected based on the mode and / or responsivity
ratio.
Stage selection is not available in HFW mode. Both arrays are set to 64 rows.
In HDR mode stage selection is determined by the selected responsivity ratio. Stage selection in
HDR mode: 2:1, 4:1, 8:1.
Array Number of Stages
Main Array 128, 64
Secondary Array 64, 16
It is important to do a flat field based on the number of stages used as a flat field done with a
different number of stages is not applicable.
Establishing the Desired Response
One of the important performance characteristics of the camera that will determine its suitability
for an application is its responsivity and the associated noise level at the system’s maximum line
rate and under the desired illumination conditions and lens configuration.
