Hi,

I am planning a series of Laser-Doppler measurements of vibrations on the human skin. I need a good reflector, that has little mass by itself and is not stiff (e.g. no band aid with a mirror). I know of some commercial products designed for skin use (e.g. Safety Skin Reflective Spread or Albedo 100 for Pets). Does anyone have experience with those or similar products or suggestions on reflective material? I considered reflective (theater) make-up, but it scatters light more instead of reflecting it.
