Claim 0:
1. An apparatus for measuring blood flow in a foot, the apparatus comprising:
a platform having a platform contact surface configured to receive the foot, the platform contact surface configured to receive a foot force having a foot force magnitude when the platform contact surface receives the foot;
a plurality of PPG sets extending through the platform contact surface, each PPG set having at least one light source and at least one light detector; and
a plurality of springs,
each PPG set being coupled with one or more of the plurality of springs,
each PPG set being movably coupled with the platform by the one or more of the plurality of springs,
each spring biased to produce a biasing force via its coupled PPG set when the platform contact surface receives the foot,
each PPG set and its corresponding one or more springs configured so that the biasing force has a biasing force magnitude that is substantially independent of the foot force magnitude.
