摘要： High speed laser scanning systems and methods are disclosed for imaging target samples. Embodiments of the laser scanning systems and methods include separating a laser beam into two or more different pathways and pulsing light along the two or more pathways. The different pathways intersect the surface of a moving mirror at different locations and light traveling in a pathway that is being approached by an edge of the moving reflective surface is turned off while light traveling in a different pathway that is farther from the edge of the moving reflective surface is turned on. Embodiments include reflective surfaces that form a rotating polygonal scanner. Further embodiments include recombining the two or more different pathways, focusing the laser light on a test sample, and imaging the light reflected from the test sample.
