24 February 2009 The speckle-free nature of photoacoustic imaging
Author Affiliations +
Photoacoustic imaging for biomedical applications has seen significant growth during the past few years. Despite its coherent nature, it possesses a unique advantage to produce images devoid of speckle artifacts. The reason responsible for this salient feature has not been addressed so far. We found this is a direct result of its extraordinary absorption contrast. Our discovery is explained using simulations based on a practical photoacoustic imaging system.
