Abstract

Hybrid unmixing technique (HyU) of this disclosure may provide enhanced imaging of multiplexed fluorescence labels, enabling longitudinal imaging of multiple fluorescent signals with reduced illumination intensities. This disclosure generally relates to imaging systems. This disclosure relates to hyperspectral imaging systems. This disclosure further relates to hyperspectral imaging systems that generate an unmixed color image of a target. This disclosure further relates to a hyperspectral imaging system that is configured to use a hybrid unmixing technique to provide enhanced imaging of a target. This disclosure further relates to a hyperspectral imaging system that is configured to use a hybrid unmixing technique to provide enhanced imaging of multiplexed fluorescence labels, enabling longitudinal imaging of multiple fluorescent signals with reduced illumination intensities. This disclosure further relates to hyperspectral imaging systems that are used in diagnosing a health condition.
