<p>In an instrument (100) generating images from the fluorescent emissions of a plurality of fluorescent dyes carried by objects in a flow stream (101), spectral dispersion is used to expand the images of the objects along one axis of a two-dimensional photosensor array (106) according to emission wavelength. The dispersion is unable to completely separate the emissions of a plurality of dyes because the emission spectra of the dyes overlap in wavelength. The method of the present invention accomplishes accurate estimation of the intensity of the light received from each of a plurality of dyes by decomposing the two dimensional spectrally dispersed images into a set of characteristic parameters using either an iterative curve fitting optimization method or a linear algebraic method.</p> |
