A method for the calibration of wideband ultrasonic sensors for optoacoustics
(American Institute of Physics, 2021-06-16)
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 ...
Software-defined optoacoustic tomography
(Optical Society of America, 2020-01)
In this work we present what we believe is the first application of software-defined optoelectronics (SDO) for bidimensional optoacoustic tomography (OAT). The SDO concept refers to optoelectronic systems where the ...
Improvement of a system for 2-D optoacoustic imaging using a deconvolution filter
(Institute of Electrical and Electronics Engineers, 2018-06)
The detection system for optoacoustic tomography(OAT) usually employs broadband piezoelectric sensors basedon polymeric materials. Polyvinylidene fluoride (PVDF) andits copolymers are amongst the most popular ones. Within ...
A Comparative Study of Time Domain Compressed Sensing Techniques for Optoacoustic Imaging
(Institute of Electrical and Electronics Engineers, 2022-04)
Speeding up data acquisition and reducing the complexity of the detection system are among the central goals for advancing optoacoustic imaging. In this way, new reconstruction algorithms using the compressed sensing (CS) ...
