Mid-infrared autocollimation for linear motion error measurement
It is known that linear motion errors for linear guides can be measured by the autocollimation method. In this case, it is necessary to install a mirror on the measurement target.

Uncertainty evaluation of multilateration-based geometric error measurement considering the repeatibility of positioning of the machine tool [PDF]
The sequential multilateration principle is often adopted in geometric error measurement of CNC machine tools. To identify the geometric errors, a single laser tracker is placed at different positions to measure the length between the target point and ...

The impact of imprecisely measured covariates on estimating gene-environment interactions [PDF]
BACKGROUND The effects of measurement error in epidemiological exposures and confounders on estimated effects of exposure are well described, but the effects on estimates for gene-environment interactions has received rather less attention.
