Time-gated parallelised interrogation of a Fabry-Perot ultrasound sensor using a camera for fast photoacoustic tomography

Abstract

Standard Fabry-Perot (FP) based scanners are typically interrogated by scanning a focused laser beam over its surface and measuring the reflected light. An alternative is to illuminate the FP sensor with a large collimated beam and measure the reflected light using a camera. This would allow the speeding up of image acquisition. To investigate this approach, a system was built and its ability to acquire full 3D photoacoustic images in times as low as 0.2 seconds demonstrated in phantoms. It was then used for in-vivo photoacoustic imaging, demonstrating the ability of the system to rapidly acquire images of the microvasculature.
