In linescan mode, the camera adds the single lines to one image of the heigth of max 1024 px. The
images are provided with no gap.
Due to aberrations at the edges of the lens, you should set an offset in the direction of Y (Offset Y, see the
following figure), generally around the half of the sensor's height (a.k.a. sensor's Y center). With Offset Y you
can adjust the scan line in the direction of motion.

In this sample, we chose an exposure time of 250 us and to ease the calculations we used 1000 px image
height
.
To get suitable image results, it might be necessary to increase the gain or the illumination.
These settings result in a frame rate of 2.5 frames per second.
To adjust the opto-mechanics (focus, distance, illumination, etc.), you can use the area mode of the sensor.
That's a main advantage of an area sensor with linescan mode compared to a linescan camera!
You will need the following pins of the mvBlueCOUGAR-X:
