If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...

Sampling Moiré methods exploit the interaction between a reference grating and an observed deformation-induced grating to generate low-frequency fringe patterns that are highly sensitive to ...

Distributed fiber-optic acoustic sensing is capable of continuously monitoring the spatially distributed evolution of environmental variables along a sensing fiber, thus has been extensively used in ...
