Abstract
(EN)
According to the present invention, disclosed is a photoacoustic scan image device, which can generate a high-resolution photoacoustic image by means of a photoacoustic sensor unit having a single channel or a low channel and variously adjust the resolution of the photoacoustic image. A photoacoustic scan image device according to one embodiment of the present invention comprises: a laser emitting unit for emitting a laser pulse at an object; a photoacoustic sensor unit for collecting photoacoustic signals generated when the object thermoelastically expands because of the laser pulse; a scan unit for scanning an inspection area of the object by moving the photoacoustic sensor unit; and a photoacoustic generation unit for generating a photoacoustic image by using the photoacoustic signals sequentially collected by the photoacoustic sensor unit.

La présente invention concerne un dispositif d'image de balayage photoacoustique, qui peut générer une image photoacoustique à haute résolution au moyen d'une unité de capteur photoacoustique ayant un seul canal ou un canal bas et ajuster de manière variée la résolution de l'image photoacoustique. Un dispositif d'image de balayage photoacoustique selon un mode de réalisation de la présente invention comprend : une unité d'émission laser pour émettre une impulsion laser au niveau d'un objet ; une unité de capteur photoacoustique pour collecter des signaux photoacoustiques générés lorsque l'objet se dilate de manière thermoélastique en raison de l'impulsion laser ; une unité de balayage pour balayer une zone d'inspection de l'objet par déplacement de l'unité de capteur photoacoustique ; et une unité de génération photoacoustique pour générer une image photoacoustique à l'aide des signaux photoacoustiques séquentiellement collectés par l'unité de capteur photoacoustique.
