Profile Measurement Using Confocal Chromatic Probe on Ultrahigh Precision Machine Tool

International Journal of Automation Technology, 2021
An on-machine measurement (OMM) system is an effective apparatus for achieving an efficient profile compensation and improving machining conditions in ultrahigh precision machining. Herein, we report a new OMM system with a confocal chromatic probe on a five-axis ultrahigh precision machine tool constructed using a real-time position capturing method ...

Metalens Enables Parallel Chromatic Confocal Imaging over a Millimeter-Scale Depth Range with an Axial Space-Bandwidth Product of 68. [PDF]

Nano Lett
Confocal microscopy provides optical sectioning and micrometer-scale resolution but remains constrained by mechanical axial scanning and bulky optics. Leveraging the intrinsic chromatic dispersion of a custom-designed metalens, we demonstrate parallel ...

Dispersion extension method for ultrasmall fiber probes in the chromatic confocal system

Optics Express
This study proposes a method for extending the dispersion range using combined gradient refractive index (GRIN) lenses. The imaging model of the probe was established based on the self-focusing characteristics of GRIN lens. The dispersion extension of the probe can be achieved using the model to optimize the probe structure while ensuring high ...

Multi-Sensor Registration in High-Precision CMM Based on a Composite Standard [PDF]

Sensors, 2018
Registration is a critical step in multi-sensor dimensional measurement. As the accuracy of registration directly impacts the quality of final results, a reference sphere as a common standard is problematic in high-precision registration.
