Patent Images

1. A system for imaging multiple features of a specimen, the system comprising:

  • one or more light sources capable of successively generating illumination beams each having a distinct wavelength band;

    a plurality of differentially excitable labels capable of labeling a specimen comprising multiple features, such that each different feature is labeled with a different differentially excitable label;

    a controller operationally associated with the one or more light sources for successively directing illumination beams onto the specimen so that each of the different differentially excitable labels is successively caused to emit an optical signal within the same wavelength band; and

    an optical system capable of collecting such emitted optical signals and forming successive images corresponding to the labeled features of the specimen on a light-responsive surface to form successive sets of image data thereof.
