a Multifocal structured-illumination PAM with grating-based beam splitting (adapted with permission from ref. 68). b System schematic of multi-focal PAM with ergodic relay. The focus plane of the microlens array is imaged onto the surface of the ER prism to illuminate the object. A single-element ultrasonic transducer is attached to a corner of the ER to detect the encoded PA signals (adapted with permission from ref. 70).
