SkLineScan: Toolbar

1

 

New line scan. All open "Signal window" windows will be closed. [F2]

3

 

"USB Camera Control" dialog for parameter settings: integration time, line frequency, synchronization 
mode, thresholding

4 5 6 7

 

Zooming in and out, separately for x- and y-achsis - applicable in "Signal window". 

 

In "Area Scan" view only 

4

 and 

5

 are available and will scale both axis proportionally.

8

 

New line scan. "Area Scan" windows will be closed, "Signal window" windows will remain open. [F2]

9

 

"Shading Correction" dialog to adjust the white balance [Alt + s]

10

 

"Gain/Offset Control" dialog, also commands input [Shif+F4]

For additional functions see the 

SK91USB3-WIN software manual

.

Start the SkLineScan program.

•  The most common functions of the line scan camera 

can be controlled by dialog boxes.

•  Commands for comprehensive camera functionality 

can be entered in the "Camera Gain / Offset Control" 
dialog.

•  For a guide on how to carry out imaging and how to 

work with the obtained data with the 

Schäfter + 

Kirchhoff

 software package, see the 

SK91USB3-WIN 

software manual

.

The SkLineScan program recog nizes the connected line 
scan cameras automatically.
•  If  the  SK8100U3JRC camera is identified correctly 

confirm with "OK". The "Signal window" graphicaly 
showing the intensity signals of the sensor pixels 
(oscilloscope display) will open. It  is responsive in 

real-time, and the zoom function can be used to 

highlight an area of interest. The oscilloscope display 

is ideally suited for parameterizing the camera, for 

evaluating object  

illumination, for  

focussing the 

image or for aligning the line scan camera correctly.
