Appeal No. 2004-0659
Application No. 09/111,978
Claim 1 (Amended) A method for high speed, scanning phase measuring of an
object at a vision station to develop physical information associated with the object, the
method comprising the steps of:
projecting a pattern of imagable electromagnetic radiation with at least one
projector;
moving the object relative to the at least one projector at a substantially constant
velocity at the vision station so as to scan the projected pattern of electromagnetic
radiation across a surface of the object to generate an imagable electromagnetic radiation
signal;
receiving the imagable electromagnetic radiation signal from the surface of the
object with a detector having a plurality of separate detector elements which are
substantially uniformly spaced;
maintaining the at least one projector and the detector in a substantially fixed
relation to each other;
measuring an amount of radiant energy in the received electromagnetic radiation
signal with the detector wherein each of the detector elements produce [images] an image
having a different [phases] 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.
