Appeal No. 2004-0659
Application No. 09/111,978
measuring an amount of radiant energy in the received electromagnetic radiation
signal with the detector wherein each of the detector elements produce an image having a
different phase of the same scanned surface based on the measurement; and
computing phase values and amplitude values for the different phases from the
multiple images.
40. New reissue application claims 30, 42, 56, 60, and 72 were
subsequently amended to add the limitation underlined in exemplary amended claim 30,
reproduced below:
Reissue Claim 30 (Amended). A method for high-speed scanning measurement
of an object at a vision station, the vision station having a detector, in order to determine
dimensional information associated with the object, the method comprising the steps of:
projecting a pattern of light;
maintaining the projected pattern of light and the detector in a substantially fixed
relation to each other;
moving the object relative to the projected pattern of light so as to scan the
projected pattern of light across an area of a surface of the object to generate an imagable
light signal;
imaging the imagable light signal onto the detector, the detector having a first, a
second, and a third detector element, wherein the area of the surface of the object is
imaged onto the first detector element at a first phase of the projected pattern of light, the
area of the surface of the object is imaged onto the second detector element at a second
phase of the projected pattern of light and the area of the surface of the object is imaged
onto the third detector element at a third phase of the projected pattern of light;
measuring with the detector an amount of light from the area of the surface of the
object to the first detector element at the first phase, to the second detector element at the
second phase, and to the third detector element at the third phase; and
computing dimensional information based on the measuring step.
