    摘要: The synchronous sampling scanning force microscope includes a reflective cantilever arm having a free end which is oscillated at a frequency different from the resonance frequency of the cantilever arm. The motion of the oscillating cantilever arm is measured, to generate a deflection signal indicative of the amplitude of deflection or phase shift of the cantilever arm. Selected portions of cycles of the output signal are sampled, for generating output signal data indicative of deflection of the near and far excursions of the probe. The method and apparatus permit monitoring of compliance of the surface of the specimen by multiple sampling at a rate greater than the period of oscillation of the cantilever probe of the microscope.

    摘要: The scanning apparatus linearization and calibration system includes an electromechanical scanner having a sample stage portion, and a deflecting member, mounted between the scanning means and a fixed mounting member, that undergoes deflection in response to displacement of the scanner sample stage portion in at least one dimension of displacement. Strain gauges are mounted to the deflecting member for measuring the deflection of the deflecting member and for generating a deflection output signal indicative of an amount of deflection of the deflecting member, to provide a highly sensitive indication of actual displacement of the sample stage of the scanning apparatus. Control circuitry also provides for open loop displacement correction and for closed loop feedback correction of the position of the scanner sample stage.

    摘要: A fiber optic switch (400) includes a fiber optic switching module (100) that receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) which may be selected as pairs for coupling a beam of light (108) between a pair of optical fibers (106). The module (100) also produces orientation signals from each deflector (172) which indicate its orientation. A portcard (406) included in the switch (400) supplies drive signals to the module (100) for orienting at least one deflector (172). The portcard (406) also receives the orientation signals produced by that deflector (172) together with coordinates that specify an orientation for the deflector (172). The portcard (406) compares the received coordinates with the orientation signals received from the deflector (172) and adjusts the drive signals supplied to the module (100) to reduce any difference between the received coordinates and the orientation signals. The switch (400) also employs optical alignment to precisely orient pairs deflectors (172) coupling a beam of light (108) between optical fibers (106).
