Were obtained by scanning the sample along the x-y plane with a step size of 5 μm. By changing the depth of the combiner in the z direction and repeating the scanning processes, a series of images were obtained. Since laser was unfocused and fixed in this experiment, the image quality depended on the acoustic focusing of the combiner. The diameter of the particle was small enough to be approximately estimated as a point source. Therefore, these images can be used to approximately evaluate the acoustic focusing performance of the combiner. A total of 18 images were obtained from 2.1 mm above the focus to 3.3 mm below it, with an axial (z-direction) interval of 0.3 mm.Figure 5a demonstrates 5 layers around the focal plane, from 1.2 mm below the focus to 1.2 mm above the focus. Figure 5b compares the focusing condition along the acoustic axis, where the blue empty dot is measured in the experiment and the red solid line is predicted by numerical simulations. Figure 5c gives the image obtained on the focal plane. Figure 5d,e plot two cross sections of the acoustic focus along x and y direction, with their simulated results. The full width at half maximum (FWHM) of the profile in the image was only approximately 183 μm in x direction and only approximately 151 μm in y direction, which was close to the simulated data at the focus in the two directions. The small focal size implied strong acoustic focusing ability and high receiving sensitivity. These experimental results demonstrate the proposed combiner can provide efficient acoustic focusing and is in good agreement with the theoretical predictions, which means strong acoustic focusing.In the second phantom experiments, we tested the resolution of the OR-PAM with the proposed optical-acoustic combiner. A bunch of carbon fibers were used as imaging objects. We took the fibers with a diameter of approximately 7 µm, placed it on a cover glass, randomly separated them with distilled water, and taped them to the cover glass with optically clear adhesive tape. The scanning step was 1 μm. Figure 6a shows the maximum amplitude projection (MAP) image of carbon fibers. The OR-PAM system obtained the geometric shape, size, and position of the carbon fibers clearly. Figure 6b is the normalized cross-sectional profile (the blue empty dots) of the carbon fiber image indicated by the arrow in Figure 6a. We took logarithm of the PA value along x direction, and applied the ordinary least squares method to get the fitting curve. By applying this Gaussian curve fitting to the profile data (red solid line), we can estimate that the FWHM along the x direction was approximately 13.2 μm. The green dashed rectangle marked an

The time delay of the PA signal at each position, an image encoded the depth information is given in Figure 8b. In the figure, the main body of the radial vascular network and branch microvasculatures distributed in the outer ring of the iris is clearly shown.Generally, the system with the proposed optical-acoustic combiner achieved high-quality images of the brain and the iris of live mice. Benefitting from high detective sensitivity and low optical disorders, the obtained images had good contrast and resolution. Both the MAP images and depth-encoded images revealed abundant details. Microvasculatures could be clearly observed. These in vivo experiments demonstrated the practicability of the OR-PAM system with the proposed optical-acoustic combiner.In comparison to the other methods, the proposed method has the following advantages. First, since the proposed system has a large acoustic NA, it has a smaller acoustic focal spot. In other words, the system is able to detect weaker signals at the acoustic focus. Second, since the acoustic propagation path in combiner is only through water and there is no other solid structure attenuating the propagation, the combiner has low insertion loss. The above two advantages promise good detection sensitivity. Third, the proposed combiner doesn’t rely on customized ultrasound transducer. Commonly used commercial transducers are suitable. Additionally, benefiting from the good sensitivity, the system might have potential to achieve better imaging depth.The scanning time of the system could be reduced by increasing the motion speed and laser repetition frequency, or enlarging the scanning step. Moreover, the size of the combiner is limited by the volume of the selected transducer. To achieve a larger acoustic NA and a long working distance, the element size of the transducer has a minimum size limit, and this can be improved. Potential applications of the OR-PAM could be clinical diagnostic imaging of eye, including choroid and retina, and the microscopic imaging of superficial and thin tissues like microvasculatures at the extremity. 4. ConclusionsThe performance of an OR-PAM system is usually closely related to its design of the optical-acoustic combiner. In this study, we proposed an optical-acoustic combiner based on an OPM and a flat acoustic reflector to achieve a high-performance OR-PAM system. We examined the acoustic focusing ability of the proposed optical-acoustic combiner by using quantitative numerical simulations and the experimental measurements. The results showed that the proposed combiner has a larger acoustic NA. Moreover, the entire ultrasonic propagation path is only through water. These characteristics of this combiner promise good detection sensitivity. Then, it was demonstrated that this imaging system has a spatial resolution of about 2.6 μm by imaging carbon fibers. Finally, in vivo imaging of the mouse brain and the iris demonstrated the practicability and potentials in biomedicine. In
