1. A spectrally-selective structured light surgical navigation system comprising: a structured light detection device comprising: an optical projection device configured to project structured light patterns onto an exposed surface of a patient, such that backscattered optical radiation is suitable for structured light detection; at least one camera configured for imaging the backscattered optical radiation; wherein said optical projection device or said at least one camera are configured such that the backscattered optical radiation is detectable within each spectral band of a plurality of spectral bands; and processing circuitry operatively connected to said structured light detection device, wherein said processing circuitry includes a processor and a memory, wherein said processor is configured to execute instructions stored in the memory for performing the steps of: controlling said structured light detection device to illuminate the exposed surface and detect images within each spectral band; process the images to generate a topological image data set associated with the exposed surface, wherein the topological image data set comprises topological image data associated with each spectral band; and generating one or more navigation images based on the topological image data set.
