Abstract
A probe for use with an imaging system, including a scanning device configured to receive a first light beam from a light source, a beam-divider configured to split the first light beam into a plurality of second light beams, and a focusing device configured to focus each of the second light beams on respective locations in an object of interest.
Claims13
A probe for use with an imaging system, said probe comprising:
- a scanning device configured to receive a first light beam from a light source;
- a beam-divider configured to split the first light beam into a plurality of second light beams;
- a focusing device configured to focus each of the plurality of second light beams on a respective location in an object of interest;
- and
- an optical-acoustic beam combiner comprising a first prism and a second prism with a fluid therebetween, the optical-acoustic beam combiner configured to merge the plurality of second light beams and acoustic signals emitted by the object of interest in response to the plurality of second light beams.
