摘要

If you have ever shone a torch onto the back of your hand, you will know that your palm glows red. Hemoglobin in the blood absorbs almost all visible radiation at wavelengths below about 600 nm, letting only red light pass through. Disappointingly, however, bones and other anatomical structures are impossible to see. Light is scattered so strongly by soft tissue that even a parallel beam becomes diffuse after travelling just a millimetre into the skin.
