Interferometric step gauge for CMM verification

Single-step superresolution by interferometric imaging.

The use of vertical-cavity surface-emitting laser (VCSEL) arrays for implementation of incoherent source superresolution is presented. The method uses an interferometer setup to obtain superresolution in a single step. The novelty of the method relies on the use of a VCSEL array as the light source, which provides a set of coherent sources which are mutually incoherent. The technique accomplish...

Polarimetric and Interferometric SAR Calibration Verification Methods

It is necessary to calibrate SAR data in order to use the data for science applications. When both polarimetric and interferometric data are collected simultaneously, these SAR data can be used for cross-calibration and verification. The frequency of polarimetric and interferometric data does not have to be the same for this purpose. For example, the NASA/JPL AIRSAR system can acquire C-band in...

A taxonomy of model-based redundancy methods for CMM online performance verification

This paper presents a taxonomy of methods for online performance verification of three-axes Coordinates Measuring Machines (CMMs). The attention is focused on analytical redundancy methods, which are based on the use of mathematical models to describe physical relationships between measured quantities. A general framework for the application of the analytical redundancy methods is presented. A ...
