A laparoscopic apparatus for imaging subsurface blood flow of tissue, the laparoscopic apparatus including a light source emitting white light via a light guide, a laser source emitting laser light via an optical fiber and a laparoscope that alternatively receives reflected laser light emitted from the laser source, and reflected white light emitted from the light source. The apparatus further includes a computing device receives the sensed resulted from the laparoscope and generates laser speckle contrast images or white light images according to an output status of the light source and the laser source, and a display that is operatively associated with the computing device and that displays at least one of the laser speckle contrast images and the white light images, where the laser speckle contrast images show the subsurface blood flow.
