The measurements of ultrasonic fields are often performed using polyvinylidene fluoride (PVDF) membrane hydrophones. Recently, optical hydrophones have gained popularity. Refractive type optical hydrophones are based on the change of refractive index at a glass-water interface when the shockwave passes the sensitive area. A major disadvantage of the optical and the PVDF hydrophones is the fact that they provide a single spot sensitive area, with the result that field measurements need a repositioning of the probe. In this work we introduce a multi-spot optical hydrophone with six measurement spots, for the single shot field measurement of shockwave fields. We measure a highly stable shockwave source with a calibrated hydrophone and the multi-spot optical hydrophone and we find good agreement for the calculated energy values of the shockwave field (depending on the energy settings 4{% ± 1{%}).
