displacement measurement pdf

In the case of inteferometric displacement measurements, these restrictions impose a 'standard quantum limit' (SQL), which optimally balances the precision of a measurement with its unwanted backaction. A known voltage is applied to the resistor ends. Displacement Sensors / Measurement Sensors; Displacement Sensors / Measurement Sensors These Sensors can be used to measure distances and heights. For high precision displacement measurements, SmarAct offers the PICOSCALE Interferometer, a powerful sensor with picometer resolution.Based on an extremely compact Michelson interferometer, non-invasive displacement measurements with low restrictions on the target reflectivity can be realized very … 0000037735 00000 n Article can not be downloaded.
