DOI: 10.1364/ol.446714
Abstract: Photoacoustic (PA) transducers are an attractive method of producing high-amplitude, high-frequency, broad-bandwidth ultrasound signals with excellent immunity to electromagnetic interference, when compared with their traditional electroacoustic counterparts. However, the lack of effective control over the… read more here.
