Abstract
In a Raman spectroscopy apparatus, exciting light is focussed on a sample () as a line focus. Spectra from points in the line focus are dispersed in rowson a CCD detector, having a two-dimensional array of pixels. The line focus moves longitudinally in a direction Y (arrow) relative to the sample. Simultaneously and synchronously, charge is shifted in a parallel direction Y' (arrow) within the CCD, so that data from a given point in the sample continues to accumulate. This ensures that the data from each sample point arises from illumination which is integrated along the line focus, and makes it easier to stitch the data together subsequently to form an image of the sample. In order to provide averaging in the X direction during fast, low resolution scanning, the line focus is swept across the sample in a zig-zag fashion, between boundary lines
