(a, c) The OCD spectroscopy approach. Though practical, it has limited spatial and spectral resolution and long scan times. (b, d) The LHSI approach developed by the research team, with a shorter scanning time and much higher spatial and spectral resolution. Each square in the grid shown in (d) corresponds to an observed “pixel.” (IMAGE)
