Patent DE-4035039-A1 (DE)
Title: Detecting movement of structured object - using CCD line detector on which image of object is formed, with transfer and shift register gates operated alternately
IPC: G01P13/00
Filed: 1990-11-04
Abstract: The method of contactlessly detecting the motion of structured objects involves using a CCD line sensor with at least two transport shift registers and forming an image of the moving object on the array.
