Abstract

The Diffuse Speckle Pulsatile Flowmetry provides an high monitoring rates of around 300 Hz for non-invasive measurement of blood flow in deep tissue, exhibiting promising potential for the monitoring various pathologies associated with abnormal blood flow.In the reported article author examined the parameter comprises this technique including speckle size and exposure time on measuere flow reading experimentally and reported how the flow measurement sensitivity was affected by these parameters.3.

Frontiers in Physics ( 2022): 925.In the reported work auhtor proposed designing of a dual-wavelength 2D fiber Bragg grating (FBG) written on a standard single-mode fiber to monitor temperature and strain simultanously. The sensor showed an high sensitivty for temperature and strain of 10.64pm/°C and 0.882731pm/uε at the central wavelength of 1548nm, while 10.74pm/°C and 0.916080pm/uε at the central wavelength of 1550nm.4.
