Abstract
High-throughput hyperspectral imaging systems are provided. According to an aspect of the invention, a system includes an excitation light source; an objective that is configured to image excitation light onto the sample, such that the excitation light causes the sample to emit fluorescence light; a channel separator that is configured to separate the fluorescence light into a plurality of spatially dispersed spectral channels; and a sensor. The excitation light source includes a light source and a plurality of lenslet arrays. Each of the lenslet arrays is configured to receive light from the light source and to generate a pattern of light, and the patterns of light generated by the lenslet arrays are combined to form the excitation light. The objective is configured to simultaneously image each of the patterns of light to form a plurality of parallel lines or an array of circular spots at different depths of the sample.
