    Abstract: A system and method for collecting Raman data sets without the “contaminating” effect of luminescence emitted photons. Using a frame transfer CCD for time resolved data collection, Raman imaging may be performed without photobleaching the sample. The system may include a light source, a frame transfer CCD, an optical lens and at least one controller. The light source illuminates the sample with a plurality of photons to generate scattered photons from the sample. The frame transfer CCD has an image array and a storage array. The optical lens collects scattered photons and directs the scattered photons to the image array. The controller transfers a Raman data set representative of the scattered photons from the image array to the storage array. The frame transfer CCD may be configured so as the image array integrates the scattered photons during a Raman integration time and the controller transfers the Raman data set from the image array to storage array during a parallel transfer time. The sum of the Raman integration time and the parallel transfer time is less than the minimum time it takes to trigger luminescence from the sample.

    Abstract: The invention relates to methods of dynamic chemical imaging, including methods of cellular imaging. The method comprises illuminating at least a portion of a cell with substantially monochromatic light and assessing Raman-shifted light scattered from the illuminated portion at a plurality of discrete times. The Raman-shifted light can be assessed at a plurality of Raman shift (RS) values at each of the discrete times, and the RS values can be selected to be characteristic of a pre-selected component at each of the discrete times. Multivariate analysis of Raman spectral features of the images thus obtained can yield the location and chemical identity of components in the field of view. This information can be combined or overlaid with other spectral data (e.g., a visible microscopic image) obtained from the field of view.
