Photoacoustic Sensor
First Claim
1. Apparatus for stimulating photoacoustic waves in a region of a body and generating signals responsive to the stimulated photoacoustic waves comprising:
- a light source that provides light that stimulates photoacoustic waves in the region;
a light pipe having an output aperture and at least one input aperture, which light pipe receives the light from the light source at the at least one input aperture and transmits the received light from the output aperture to illuminate the region; and
at least one acoustic transducer that generates signals responsive to acoustic energy from the photoacoustic waves that is incident on the optical output aperture.

Abstract
Apparatus for stimulating photoacoustic waves in a region of a body and generating signals responsive to the stimulated waves comprising: a light source (27) that provides light that stimulates photoacoustic waves (54) in the region; a light pipe (26) having an output aperture (80) and at least one input aperture, which light pipe receives the light from the light source at the at least one input aperture and transmits the received light to illuminate the region from the output aperture; and at least one acoustic transducer (22) that generates signals responsive to acoustic energy from the photoacoustic waves that is incident on the optical output aperture.
