A method is provided for measuring a response to a stimulus of a plurality of samples spots of a sample using a measuring system having a measurement range to generate an image of the sample in digital space. The snowboard binding includes a base member, a rear binding arrangement, and a front binding arrangement. An oxide film is formed on only the mesa top which is selectively grown in a self-align process to grow a current block layer. Collection optics then gather phase modulated light scattered by the surface and direct the phase modulated light to an optical processor to produce a signal representative of the ultrasonic displacements with an improved SNR.
