In 24-hour Non-invasive Blood Pressure (NIBP) measurement, most of the automatic devices use oscillometric method. Accurate measurement of BP at finger using an Oscillometric Waveform (OMW) remains a ...

An all-fiber linear sampling device for dual-comb time-of-flight (TOF) distance measurement is demonstrated. We studied the impact of optical filter and adjustable attenuator on the symmetry of the ...
