1. A system for detecting deformation of a membrane comprising:

  • a membrane having a surface;

    an emitter disposed to impinge, upon a segment of said surface, electromagnetic radiation, with a portion of said electromagnetic radiation impinging upon said segment being reflected therefrom along a reflected path; and

    a detector having an electromagnetic radiation collection area lying in said reflected path, with said segment being adapted to reflect, in a first state, substantially all electromagnetic radiation impinging thereupon along said reflected path, defining reflected radiation, and scattering, in a second state, a portion of said reflected radiation away from said reflected path.
