Camera Orientation
The diagram below shows the orientation of forward and reverse with respect to the camera body.
Note:
The diagram assumes the use of a lens on the camera, which inverts the
image.
Figure 27: Example of Object Movement and Camera Direction
The diagram shows the designated camera direction. However, due to the characteristics of the
lens, the direction of the objects motion is opposite to the image motion direction.
Some inspection systems require that the scan direction change at regular intervals. For example,
scanning a panel forwards, coming to a stop and then scanning backward as the camera
’
s field of
view is progressively indexed over the entire panel.
It is necessary for the system to over-scan the area being imaged by at least the 128 stages of the
TDI sensor before the direction is changed. This ensures that valid data will be generated on the
return path as the camera
’s
field of view reaches the area to be inspected.
