Abstract
An experiment is conducted that successfully reduces the amount of aberration detected in a reconstructed hyperspectral datacube. The correction alleviates an unnoticed rotational misalignment in the calibration of our near-infrared flash hyperspectral imager. This alteration induces a spherical-aberration-like artifact as well as spectral defects because of the three-dimensional hyperspectral quality of the data. This artifact, which would cause severe misregistration of the spatio-spectral information, is correctable post detection.
