Spatial resolutions of the handheld PAM probe. (a) PA MAP image of part of a black and white pattern. (b) LSF fitting from the experimental data across the line a-a’ in (a). (c) Cross-sectional PA B-scan image of a carbon fiber. (d) LSF fitting from the experimental data across the line b-b’ in (b). FWHM, full width at half maximum; MAP, maximum amplitude projection; ESF, edge spread function; and LSF, line spread function.
