Abstract
A method for visualizing objects under light obstructing barriers of a target, the method including emitting an ultrasound wave and a laser wave towards a target, detecting a reflected laser wave is detected by optical means, analyzing the optical signal at the ultrasound frequency with demodulation means, generating ultrasonic image characteristics of the interaction of the ultrasound with the different layers of the target, and generating an optical image of the target obtained using optical imaging, wherein the ultrasonic image is fused with the optical image and the fused image is displayed on a display device.
