1. A system for remapping data obtained from a scanning beam device, the system comprising: a processor; and a memory coupled to the processor, the memory configured to store a plurality of code modules for execution by the processor, the plurality of code modules comprising, a calibration code module for capturing positions of an illumination spot being scanned in a scan pattern for device calibration prior to scanning a target site, and synchronizing the captured positions with corresponding time points in the scan pattern, a storage code module for storing the captured positions of the illumination spot with the corresponding time points, and an image code module for constructing an image of the target site on a pixel-by-pixel basis, wherein the image code module is configured to place collected backscattered light collected at a plurality of time points in a pixel position corresponding to the stored, captured positions at the corresponding time points in the scan pattern.
