摘要：
Disclosed herein is a novel technique that employs non-invasive ultrasound for spatiotemporal modulation of the refractive index in a medium to define and control the trajectory of light within the medium itself, thereby creating a virtual sculpted lens. By varying the amplitude of ultrasonic waves in the medium, the numerical aperture (NA) value of the virtual sculpted lens can be changed. The location of the focus of the virtual sculpted lens can be precisely scanned within a scattering tissue.
