..., principally accelerometers and pressure, temperature and displacement sensors, used in environments characterised by elevated temperatures, radiation and high shock and vibration levels. Findings The paper shows that a range of different strategies is employed to allow sensors to operate in extreme...

...Kin Yen; Mani Ratnam Purpose Researchers in the past have used Fourier transformation method to determine the in‐plane displacement components from moiré fringes generated by a pair of overlapping circular gratings. In this approach it is necessary to assume that the transmittance is sinusoidal...
