Images are captured as Ix,yðÞand scanned across the second spatial dimension,
y [26]. This approach is commonly used with confocal microscopy [27]. For most
applications, the number of wavelengths to be measured is much smaller than the
spatial dimension of the sample, and hence the detector requires a significantly
smaller number of detector elements for the acquisition, relative to CCD-based
methods. This results in a much longer acquisition time in comparison to the
CCD-based systems in order to achieve the same SNR. This method is most
commonly used for brightfield microscopy, but it is applicable for fluorescence
microscopy as well.
