Abstract
To localize and monitor the blood content in tissue we developed a very sensitive double-ring photo-acoustical detector. PvdF has been used as piezo-electric material. In this detector also a fiber for illumination of the sample is integrated. This detector has the advantage that it is very sensitive in the forward direction. A ratio of FWHM to depth of 1:70 can be obtained with this detector.
