Abstract
A spectral imaging system includes an objective lens system, an optical splitter, a dispersion system, and an optical combiner. The optical splitter is arranged to be in an optical path of an object being imaged through the objective lens system to provide an imaging optical path and a spectrometer optical path. The dispersion system is arranged in the spectrometer optical path. The optical combiner is arranged in the imaging optical path and a path of dispersed light from the dispersion system to combined dispersed light with a corresponding optical image of the object.

A spectral imaging system, comprising:
- an objective lens system;
- an optical splitter arranged to be in an optical path of an object being imaged through the objective lens system to provide an imaging optical path and a spectrometer optical path;
- a dispersion system arranged in the spectrometer optical path;
- an optical combiner arranged in the imaging optical path and a path of dispersed light from the dispersion system to provide combined dispersed light with a corresponding optical image of the object;
- and
- a two-dimensional image sensor arranged in a path of the combined dispersed light with the corresponding optical image of the object,
- wherein the combined dispersed light with the corresponding optical image of the object are spatially overlapping on the two-dimensional image sensor, and
- wherein the two-dimensional image sensor captures the combined dispersed light with the corresponding optical image in a single frame.
A method of spectral imaging comprising:
- imaging an object through an objective lens system along an optical path;
- splitting the optical path of the object being imaged to provide an imaging optical path and a spectrometer optical path;
- dispersing light in the spectrometer optical path;
- and
- combining the dispersed light from the spectrometer optical path with a corresponding optical image of the object from the imaging optical path;
- and
- imaging the combined dispersed light with the corresponding optical image of the object with a two-dimensional image sensor,
- wherein the combined dispersed light with the corresponding optical image of the object are spatially overlapping on the two-dimensional image sensor, and
- wherein the two-dimensional image sensor captures the combined dispersed light with the corresponding optical image in a single frame.
