Abstract

A novel photoacoustic remote sensing (PARS) microscopy architecture is explored which replaces the traditional continuous-wave detection source with a pulse-sampling approach. This novel optical processing method is demonstrated on live vasculature networks with significant reductions in detection-source sample exposure by around two orders of magnitude. This architecture paves the way forward for more advanced proposed single-wavelength PARS architectures that may provide drastically improve performance in chromatic-sensitive scenarios such as posterior ophthalmic imaging and micro-endoscopy devices. Both the current pulsed-detection PARS and the proposed single-wavelength PARS are discussed and explored in detail.
