Abstract
Laser light is emitted from a laser into a scattering layer. An ultrasound signal is emitted into a sample. A signal is generated with a light detector in response to a measurement beam of laser light exiting the light scattering layer into the light detector. At least a portion of the measurement beam formed between the laser and the light detector is wavelength-shifted by the ultrasound signal subsequent to the ultrasound signal propagating through the sample.
Claims20
An imaging system comprising:
- a light scattering layer;
- a laser configured to emit laser light into the light scattering layer, wherein the light scattering layer is configured to scatter the laser light;
- a light detector configured to generate a signal in response to a measurement beam of the laser light exiting the light scattering layer into the light detector;
- and
- an ultrasound emitter configured to emit an ultrasound signal into a sample, wherein the measurement beam formed between the laser and the light detector is positioned to receive an ultrasound exit signal of the ultrasound signal exiting the sample.
