Abstract

In Photoacoustic Remote Sensing (PARS) microscopy, a pulsed excitation beam is co-focused with a continuous-wave interrogation beam to acquire photoacoustic signals in an all-optical non-contact way. This study implements a resonant deformable mirror (DM) as the active focal control element in PARS. The surface of the DM is deformed by a time-varying actuation force tuned to match the resonance frequency of the defocus mode. In preliminary experiments using the DM as a focusing element, a 5cm focal shift was realized. The Adaptive Optics (AO)-PARS is a promising technology for axial scanning, multi-wavelength imaging, and aberration correction applications.
