In science:

Double–differencing involves subtracting the data between the two nod positions to remove both long term drifts in the data (Holland et al. 1999) and a systematic effect which may be due to differential illumination (Zemcov et al. 2005).

350 micron Polarimetry from the Caltech Submillimeter Observatory
He described the application of the ‘nod and shuffle’ (also known as ‘va et vient’) and ‘micro-slit’ techniques, which together allow near-optimal sky-subtraction at faint magnitudes and a greatly increased multiplex gain.
Redshift Surveys and Cosmology
This exact differential beam-switching approach means that the ob ject and the sky are observed through the same part of the slit (or the same fibre) and with the same pixels of the detector, but avoids the extra read-noise imposed by simply nodding between exposures.
Redshift Surveys and Cosmology
At longer wavelengths, since we recorded data using only the LL2 module, the local background was subtracted by differencing the two nod positions along the slit.
