Laser Speckle Imaging of a Finger by Scattered Light Optics

摘要：

We have demonstrated Laser speckle imaging of a finger with an optical configuration based on scattered light deffection. Laser light enters a light-guide from its edge and propagates inside. A finger in contact with the light-guide scatters the light and the leaking light is imaged by a camera placed nearby. The speckle image fluctuates with time because the light scattered by the blood flowing inside the finger generates interference patterns varying with time. When the level of the blood flow is decreased by occlusion, the temporal randomness of the speckle image subsides.
