Abstract

We show that a flat plate acoustic encoder can enable fast, single-sensor photoacoustic imaging. To demonstrate the concept, we used an off-the-shelf microscope slide with a sample consisting of black tape. The glass slide needs only to be calibrated once through raster scanning. Using a different glass slide, an image of a patterned black tape was obtained within 5 seconds. This represents a 480 times imaging time reduction compared to a raster-scan based system for a similar field of view . Our result shows that a simple, flat plate encoder can be a practical solution towards fast, single-sensor photoacoustic imaging.
