1. A human body vibration analysis system comprising:
a first light source configured to illuminate a surface of the human body from a first angle, wherein the first light source generates a first set of lighted features, wherein the first set of lighted features comprise a first shape;
a second light source configured to illuminate a surface of the human body from a second angle, the second angle different than the first angle, wherein the second light source generates a second set of lighted features, wherein the second set of lighted features comprise a second shape distinguishable from the first shape of the first set of lighted features;
a camera configured to detect light reflected from the surface of the human body; and
a control circuit configured to receive an input from the camera and assess spatial vibration as a function of location on the surface of the human body;
wherein each of the one or more of the lighted features within the first set of lighted features and the second set of lighted features can be displaced in any direction a distance from a starting position to a displaced position on the human body in response to a vibratory signal from the human body.
