Investigation of an advanced micro-inductive sensor

Advanced Features and Industrial Applications of FPGAs—A Review

“…In the aforementioned work, all these elements are external to the FPGA, so performance could be improved (and chip count reduced) by using the embedded resources of these types available in current devices. This is in general true for many instrumentation and measurement circuits using FPGAs (like the ones proposed in [78] for the characterization of inductive microsensors, in [79] for DC leakage current sensors, in [80] for frequency measurement in MEMs accelerometers, or in [81][82] for microgripper control) as long as the resolution, sampling rate, etc. of the embedded analog blocks are enough for the target applications.…”

Fiber optic displacement measurement model based on finite reflective surface

“…5. The unit of x axis and y axis is μm while the unit of z axis is nW/(μm) 2 . At the beginning of above process, the LID on the plane of receiving fiber's end face equals zero, and then the light intensity becomes larger and the range of the LID expands until the light intensity falls back to zero again in the end.…”

“…However, it has a limited measurement range and high cost while it is hard to meet its high-level application requirements. The inductive displacement sensor has long measuring range with accuracy up to 0.1 µm, and its dynamic characteristics are not so high comparatively [2]. Laser interference displacement sensor has large measurement range and high accuracy of nanometer level, as well as the ability of measuring linear and angular displacement at the same time.…”
