Abstract
This invention concerns spectroscopy apparatus comprising a light source arranged to generate a light profile on a sample, a photodetector having at least one photodetector element for detecting characteristic light generated from interaction of the sample with light from the light source, a support for supporting the sample, the support movable relative to the light profile, and a processing unit. The processing unit is arranged to associate a spectral value recorded by the photodetector element at a particular time with a point on the sample predicted to have generated the characteristic light recorded by the photodetector element at the particular time based on relative motion anticipated to have occurred between the support and the light profile.
