Abstract
Disclosed herein is a novel reconfigurable spatial and temporal light modulation method that exploits the imaging medium itself by employing a multi-element ultrasonic transducer array as an in-situ acoustic modulator. The medium density can be modulated using different ultrasonic pressure patterns to pattern an incident collimated beam of light.
