Abstract

In this work, we theoretically and experimentally deal with photoacoustic resolution enhancement by means of saturated modulation quenching. It is shown that experimental systems for resolution enhancement with saturated modulation quenching in fluorescence microscopy are not necessarily suited for photoacoustic modulation quenching. Here, we show that modulation quenching is not limited to fluorescent dyes but can be also applied to metallic nanoparticles. For modulation quenching in photoacoustic microscopy it is sufficient that the signal saturates with increasing excitation intensity.
