Electrically switchable dual-focus metalens for depth-extended in vivo photoacoustic imaging of ophthalmic vascular disease

High-resolution three-dimensional imaging is essential for visualizing fine biological details. Unlike conventional optical imaging, photoacoustic (PA) imaging provides volumetric imaging by capturing time-of-flight ultrasound waves generated from optical absorption within tissues. Optical-resolution photoacoustic micr...
