    • A probe system includes an imager and an inspection light source. The probe system is configured to operate in an inspection mode and a measurement mode. During inspection mode, the inspection light source is enabled. During measurement mode, the inspection light source is disabled, and a structured-light pattern is projected. The probe system is further configured to capture at least one measurement mode image. In the at least one measurement mode image, the structured-light pattern is projected onto an object. The probe system is configured to utilize pixel values from the at least one measurement mode image to determine at least one geometric dimension of the object. A probe system configured to detect relative movement between a probe and the object between captures of two or more of a plurality of images is also provided.

    • A system for determining an object distance z includes a plurality of light emitters. A group of at least one of the plurality of light emitters includes an emitter group, and the pattern projected when one emitter group is emitting includes a fringe set. The light pattern of one fringe set exhibits a phase-shift relative to the light patterns of the other fringe sets, and the phase-shift varies as the distance from the origin of the plurality of fringe sets varies. The system further includes a processing unit that is configured to compute a ripple metric value associated with each of a plurality of possible z values. The processing unit is further configured to determine an approximated z value using the computed ripple metric values. A probe system is also provided. The probe system is configured to project a plurality of fringe sets from the probe onto an object. The light pattern of one fringe set exhibits a phase-shift relative to the light patterns of the other fringe sets, and the phase-shift varies as the distance from the origin of the plurality of fringe sets varies. The probe system is further configured to compute a ripple metric value associated with each of a plurality of possible z values, where z is an object distance. The probe system is also configured to determine an approximated z value using the computed ripple metric values. A method for determining an object distance z is also provided.
