|  This system is used in applications such as video camera production to ensure
that the cameras produce true images without any occlusions.
It is also used for inspection of endoscopes at point-of-use
by medical professionals. The vision inspection system
had to first find the focal length of the lens and
then test the integrity of the lens system at this
natural focal length using an array of optical analysis
algorithms native to the FlexAuto control software.
The
inspection system uses FlexAuto to advance the camera
through the focal plane of the lens with a precision
servo motor while simultaneously acquiring and storing
images to memory. A total of 30 images are taken
at different focal planes over a travel distance of
30
thousandths of an inch. The software analyzes each
image to determine the image in best focus. Five
regions of interest are then applied to this image
to measure
the overall image quality of the lens assembly.
