The biological effects of the signals produced by X-ray and ultrasound equipment strongly depend on their intensity. Some articles were published addressing the use of pyroelectric sensors to measure the intensity of X-rays ...

The detection of ultrasound via optical resonators is conventionally performed by tuning a continuous-wave (CW) laser to the linear slope of the resonance and monitoring the intensity modulation at the resonator output. ...

Sensors based on surface plasmon resonance present attractive features for the detection of narrow acoustic pulses since they can behave as quasi-point detectors. In order to detect fast ultrasound pressure waves, the ...

Currently, the proliferation of interconnected smart devices is related to smart urban management. These devices can process sensor data in order to obtain significant information. This information can be provided to the ...

A method for calibration of ultrasonic sensors for optoacoustics that provides both frequency response and sensitivity is presented. In order to obtain the bandwidth and the frequency response of an uncalibrated sensor, a ...

In this paper, we report on the development of an intensity-modulated fiber-optic sensor for angular displacement measurement. This sensor was designed to present high sensitivity, linear response, and wide bandwidth and, ...
