Abstract:	The mechanical response to electrical stimuli of the human membrane represents an important area of research in medicine. A linear sensing system was designed and fabricated to measure the displacements (along a specified direction) and the frequency response of a ear membrane, the Outer Hair Cell (OHC). The output of this system was a voltage proportional to the instantaneous position of the bimorph and could be displayed on an oscilloscope. The system consisted of optics to project the image of the vibrating membrane onto a Linear CCD Camera and electronic analog and digital circuitry which produced an instantaneous voltage proportional to the position of the edge of the OHC. It was designed to observe opaque and partially transparent objects and even objects with completely transparent holes at various locations. The system was successfully tested with a CCD clock rate of 2.5Mhz, using an opaque object at five fixed object locations. Object frequencies of 1Khz and spatial resolution of 1411m, are within the capability of the designed system. With higher speed circuitry, object movements up to 15Khz can be measured.
