AN APPARATUS CONFIGURATED TO AND A PROCESS TO PHOTOACOUSTICALL IMAGE AND MEASURE A STRUCTURE AT THE HUMAN EYE FUNDUS

An apparatus configured to photoacoustically image and measure a structure at the human eye fundus or components, substances, cells, tissue, or analytes within the eye and within the blood vessels of the eye including an emitter element for emitting electro-magnetic radiation, a transition element for delivering the electro-magnetic radiation into an eye, a detection element for detecting an acoustic wave and converting the acoustic wave into a digital wave signal, an analysis element for processing the digital wave signal into an image or measurement or both, and a display element for displaying a representation of the image and/or the measurement. The apparatus additionally includes a coupling member, the coupling member being configured and arranged to acoustically couple the eye to the detection element such that the acoustic wave generated within the eye can be guided onto the detection element.
