Abstract
Robotic machines such as coordinate measuring machines, contour projectors and other optical measuring machines are provided wherein a pulsed light is used to 'freeze' the dimensional or positional data. The light source of an electro-optical sensor which in motion on the machine during an inspection operation is pulsed responsive to a triggering pulse from an encoder. Where the motion is in more than a single axis, the triggering pulse can be provided from that encoder which experiences the most rapid motion or which is associated with the direction of the greatest dimension change of the part under inspection. Several different forms of position encoding apparatus are also disclosed.
