Abstract:
Provided are a laser speckle contrast imaging method, a laser speckle contrast imaging system, and an apparatus which includes the laser speckle contrast imaging system. The laser speckle contrast imaging system includes a laser light source configured to irradiate laser beams toward a subject, the laser beams having a plurality of wavelength bands and different surface transmittances with respect to the subject. An imaging unit is configured to acquire speckle images by capturing images of speckles by using an image sensor, the speckles being formed when the irradiated laser beams are scattered from the subject. A signal processor is configured to convert the acquired speckle images into speckle contrast images and to acquire a compensated speckle contrast image by compensating for a change caused by a movement of the subject.
