ABSTRACT:
A polar coordinate-based profilometer includes a base, a rotary stage, a linear stage, and a probe device. The rotary stage is mounted on the base and includes a rotary table rotatable about a vertical axis oriented orthogonal to the base. The linear stage is mounted on the rotary table and is rotatable therewith. The linear stage includes a linear slide member that is translatable along a radial axis orthogonal to the vertical axis. The probe device is mounted on the linear slide member and is translatable therewith. The probe device includes a probe tip that is linearly displaceable along the radial direction and communicates with a linear displacement-sensing transducer. Alternatively, the probe device scans an object without contacting the object. Methods are provided for measuring an object based on polar coordinates, and correcting for misalignment prior to measurement.
