Abstract
The present disclosure describes a fast-scanning optical-resolution photoacoustic (fsOR-PAE) endoscope for imaging vasculature within tissues in vivo that includes an ultrasonic transducer and a scanning mirror within a lumen of an elongate casing. The scanning mirror is configured to direct the laser pulses from the pulsed laser source to a focal spot outside the casing in a scanning pattern via an imaging window formed in the casing. The scanning mirror is further configured to direct a plurality of photoacoustic signals from the focal spot to the ultrasonic transducer via the imaging window.
