A device and method for imaging vasculature are provided. The device includes an imaging probe to be inserted into a vasculature. The imaging probe emits infrared light through blood toward the vasculature, and gathers reflected from the vasculature for imaging. The device includes an infrared light source optically coupled to the imaging probe to provide infrared light, and an infrared light detector optically to the imaging probe to generate an imaging signal from the reflected light that is gathered. The device further includes a controller coupled to the infrared light source and coupled to the infrared light detector to generate an image of the vasculature from the imaging signal. The controller may employ ballistic photon imaging techniques, gated imaging techniques, polarizing light imaging techniques, structured light imaging techniques, and the like.
