Abstract:
A system for multimodal laser speckle imaging may include a first light source positioned to emit laser light toward a target, a second light source positioned to emit light toward the target, a camera positioned to receive light scattered from the target, and a processor. The processor may be programmed to receive from the at least one camera at least one image of the target as illuminated by the laser, obtain a laser speckle contrast image of the target from the at least one image of the target as illuminated by the laser, receive from the at least one camera at least one image of the target as illuminated by the second light source, divide the laser speckle contrast image into subparts, and divide the at least one image of the target as illuminated by the second light source into identical subparts, determine whether each subpart includes a feature of a certain type by combining each subpart of the laser speckle contrast image with the at least one image of the target as illuminated by the second light source and comparing the combination with one or more criteria, and out-putting the location and type of features detected in a subpart of the images.
