More Information
Summary:An ultrasound emitter launches an ultrasonic signal into a diffuse medium such as tissue. The diffuse medium is illuminated with an infrared illumination signal. activating an ultrasound emitter to launch an ultrasonic signal into a diffuse medium. An infrared reference beam is interfered with an infrared exit signal having an infrared wavelength that is the same as the infrared illumination signal. An infrared image is captured of the interference of the infrared reference beam with the infrared exit signal.
