摘要： A controller for cantilever-based instruments, including atomic force microscopes, molecular force probe instruments, high-resolution profilometers and chemical or biological sensing probes. The controller samples the output of the photo-detector commonly used to detect cantilever deflection in these instruments with a very fast analog/digital converter (ADC). The resulting digitized representation of the output signal is then processed with field programmable gate arrays and digital signal processors without making use of analog electronics. Analog signal processing is inherently noisy while digital calculations are inherently “perfect” in that they do not add any random noise to the measured signal. Processing by field programmable gate arrays and digital signal processors maximizes the flexibility of the controller because it can be varied through programming means, without modification of the controller hardware.

摘要翻译：用于基于悬臂的仪器的控制器，包括原子力显微镜，分子力探针仪器，高分辨率轮廓仪和化学或生物传感探针。控制器采用非常快速的模拟/数字转换器（ADC）对通常用于检测这些仪器中的悬臂偏转的光检测器的输出进行采样。然后，利用现场可编程门阵列和数字信号处理器对输出信号产生的数字化表示进行处理，而不利用模拟电子装置。模拟信号处理本质上是嘈杂的，而数字计算本质上是“完美的”，因为它们不会对测量的信号增加任何随机噪声。通过现场可编程门阵列和数字信号处理器的处理可以最大限度地提高控制器的灵活性，因为它可以通过编程手段进行变化，而无需修改控制器硬件。

摘要： A single housing with a non-ferromagnetic piezo-driven flexure has primary and secondary coil forms of different diameters, one coaxially inside the other, integrated in the flexure. The cylinders defining the planes of the primary and secondaries do not spatially overlap. The secondary coil forms may be wound in opposite directions and wired to provide a transformer device. Movement of the primary relative to the secondaries in the direction of the central axis of the coils can be differentially detected with high precision.

摘要： Techniques for coupling with devices that convert displacements into differential voltages and improve the sensitivity of such devices. A transducer operates based on changes of inductances between primary and secondary of a transformer to produce a differential signal that includes a noninverted signal and an inverted signal. A switch receives the noninverted signal and the inverted signal. A processor creates a square wave signal for driving the transducer input, and also digitally creates an inverted transducer output. A filter operates to filter the square wave output from the processor to produce a substantially single frequency signal at a specified timing having a specified phase relationship relative to the first phase inversion signal based on instructions that are executed by the processor.
