WebThe principal of the photoacoustic effect is simple. Nanosecond pulsed laser light is used to illuminate the tissue. Chromophores such as hemoglobin and red blood cells absorb the light which causes local heating and thermoelastic expansion. Pressure or sound waves are emitted and detected by our ultra high frequency transducers.

Photoacoustic Imaging: Principles and Applications

Photoacoustic spectroscopy is the measurement of the effect of absorbed electromagnetic energy (particularly of light) on matter by means of acoustic detection. The discovery of the photoacoustic effect dates to 1880 when Alexander Graham Bell showed that thin discs emitted sound when exposed to a beam of sunlight that was rapidly interrupted with a rotating slotted disk. The absorbed energy from the light causes local heating, generating a thermal expansion which cre… http://www.centralcoastpictures.com/ WebJan 1, 2016 · Abstract.
