Terms & Conditions of Use

This study introduces a noncontact laser tracker method using temporal aliasing to measure moving objects as if they were stationary. This technique enables accurate dynamic state measurement without needing the laser tracker to follow the object.

Area of Science:

Metrology
Optical Measurement
Physics

Background:

Laser trackers are crucial for precise spatial measurements.
Measuring dynamic objects with laser trackers typically requires them to follow the object's motion.
Existing methods face challenges in accurately capturing the dynamic state of moving objects.

Purpose of the Study:

To present a novel noncontact technique for measuring moving objects using a laser tracker.
To enable dynamic state measurement of objects without requiring the laser tracker to track their motion.
To validate the technique's accuracy through controlled experiments with rigid and nonrigid bodies.

Main Methods:

Utilizing temporal aliasing to decompose an object's dynamic motion into a stationary frame of reference relative to the laser tracker.

Employing a Pixel Probe with three cameras, whose frame rates are adjusted to alias motion.

Triggering cameras at specific frequencies to make the moving object appear stationary to the measurement system.

Main Results:

Demonstrated accurate spatial metrology on dynamic objects by making them appear stationary.
Validated the technique by comparing measurements of rigid targets under static and dynamic conditions.
Successfully measured the 3D motion of a rotating nonrigid body, determining its rotation frequency with less than 1% error.

Conclusions:

The developed technique allows for noncontact, dynamic measurement of objects without active tracking.
This method decouples object motion from laser tracker motion, facilitating accurate dynamic characterization and calibration of laser trackers.
The technique shows potential for advancing metrology in dynamic environments and validating physical models like Newtonian mechanics.
