英文摘要	The optimal photoacoustic probe design is the key to obtain highest imaging sensitivity in photoacoustic computed tomography. Two commonly used probe design types are dark- and bright-field designs. We proposed a design for photoacoustic probe called quasibright-field illumination and compared the performance of all three kinds of probes theoretically and experimentally. Our conclusion is that the proposed quasibright-field illumination photoacoustic probe is superior compared to the existing probe designs as demonstrated. However, each type of illumination should still have its own advantages under certain circumstances. The dark-field illumination is capable of minimizing surface interference signals and reducing their contributions to the background of deeper signals. Hence, it should perform better when imaging samples with high optical absorbance at the surface layer. The bright field may perform better under circumstance when phase distortion is less. We also designed and fabricated three kinds of probes using a single multimode optical fiber for laser energy delivery instead of fiber bundle. Single fiber probes are low cost, transmit laser energy efficiently, and are compact for easy handling. Thus, our study not only provides a method for probe design but also a guidance for cost-effective transducer array-based photoacoustic probe design and manufacturing in the future.
