Abstract
A system and method for visualizing a biological sample. One or more spectra are selected for illuminating the biological sample to indicate one or more chemicals in the biological sample. The biological sample is illuminated with the one or more spectra. Reflected light is analyzed to determine characteristics of the biological sample.
Claims23
A method for visualizing a biological sample, the method comprising:
- selecting a first, second and third spectra for illuminating the biological sample to indicate one or more chemicals in the biological sample, wherein the third spectrum is a summation of the first and second spectra;
- successively illuminating the biological sample with the first, second and third spectra;
- analyzing reflected light from the first, second and third spectra to determine characteristics of the biological sample.
A system for performing hyperspectral imaging, the system comprising:
- a hyperspectral illuminator configured to illuminate a target utilizing a plurality of spectra;
- a camera in communication with the hyperspectral illuminator and configured to capture one or more images for each of the plurality of spectra;
- a data processing system controlling the hyperspectral illuminator and the camera, the data processing system processes data captured by the camera, the data processing system triggers illumination of the target for each of the plurality of spectra, the data processing system controls exposure of the camera for each of the plurality of spectra and at least one exposure is a different time period.
A method for performing imaging, comprising:
- illuminating a target with a plurality of spectra;
- exposing an image sensor of an imaging system for one of a plurality of time periods associated with each of the plurality of spectra, wherein at least one time period is a different length;
- processing reflectance images from the target utilizing chemometric algorithms;
- and
- visualizing one or more chemicals in the target.
