Figure 4: wxPropView - Triggered acquisition with area-scan cameras

17.5.3

EnhancedRawLineAcquisition Mode

The camera also offers a special mode called

"Enhanced Raw Line Acquisition Mode"

. It provides a raw "green"

pixel value for each point of an imaged object and, in addition, either a raw "red" or a raw "blue" pixel value (for more
details please have a look at the camera's manual). In sum, you can say that this is a double exposure of the same
line. For this, you will need a pulse multiplication.
