摘要：
A kind of system for the imaging of multi-mode laser speckle may include that a first light source is positioned against target sending laser, is located towards the second light source that target issues light, a camera positions of the light of scattering are received from target and a processor. From pass through at least one image of at least one video camera of same target to be illuminated of laser, processor may be programmed to reception, a contrast of laser speckle pattern image of target is obtained from least one image of the same target to be illuminated by laser, as received by the way that second light source is to be illuminated from least one image of at least one video camera of target, contrast of laser speckle pattern image is divided into subassembly, except at least one image of the same target to be illuminated by second light source is divided into identical subassembly, determine whether that each subassembly includes that the feature of a certain type uses at least one image of each subassembly target in conjunction with contrast of laser speckle pattern image such as second light source to be illuminated and compares the combination with one or more standards, export position and the type of the feature detected in a subassembly of image.
