CCD imaging device for high speed profiling

Year	Description
1997	Invention patented by Bojko Vodanovic on September 1st, 1997. Abstract: The present invention provides a method and apparatus for increasing the frame acquisition rate of an interline transfer CCD sensor by triggering the charge transfer signal TR, which controls the shift of the electrical charges from the light-sensitive cells into the vertical shift register, more than once per frame period, so that more than one image is acquired in the same frame, one above the other. The apparatus is used primarily for surface geometry inspection of high-speed moving objects, wherein acquired CCD images are thin, substantially horizontal profile lines.
