  • ORPAM

Optical resolution photoacoustic microscopy (ORPAM),benefiting from rich optical contrast, scalable acoustic resolution,and deep penetration depth, is of great importancefor the fields of biology and medicine. However, limitedby the size and performance of reported optical/acousticscanners, existing portable/handheld ORPAMs are bulkyand heavy, and suffer from low imaging quality/speed.Here, we present an ultracompact ORPAM probe, whichis miniature and light, and has high imaging quality.The probe only weighs 20 grams and has an outer sizeof 22 mm × 30 mm × 13 mm, a high lateral resolution of3.8 μm, and an effective imaging domain of 2 mm × 2 mm.To show its advantages over existing ORPAMs, we applythis probe to image vasculatures of internal organs in arat abdominal cavity and inspect the entire human oralcavity.
