This laser scanning imaging device is provided with: a laser light generating device (11) a scanning illumination optical system (20) that scans laser light on the back of the eye (Er) and a light receiving optical system (40) that receives reflected light reflected from the back of the eye (Er). The scanning illumination optical system (20) has a resonant scanner (25) that scans the laser light back and forth, and the resonant scanner (25) outputs a timing signal according to the back and forth scanning of the laser light. Frame images are constructed on the basis of forward path scanning images obtained by the forward scanning of the laser light by the resonant scanner (25) and return scanning images obtained by return scanning of that laser light, from a received light signal of a light receiving sensor (44) in a light receiving optical system (40). A period measuring unit that measures the period of the timing signal is provided. On the basis of the timing signal period measured by the period measuring unit, a scanning end edge for the forward path scanning range which forms the forward path scanning images and a scanning start edge for the return path scanning range which forms the return path scanning images are made to match in the scanning direction, and frame images are constructed.Ce dispositif dimagerie à balayage laser est prévu avec : un dispositif de génération de lumière laser (11) un système optique déclairage à balayage (20) qui balaie une lumière laser sur larrière de lœil (Er) et un système optique de réception de lumière (40) qui reçoit la lumière réfléchie depuis larrière de lœil (Er). Le système optique déclairage à balayage (20) a un scanner résonant (25) qui balaie la lumière laser en va-et-vient, et le scanner résonant (25) délivre en sortie un signal de synchronisation selon le mouvement de va-et-vient de la lumière laser à balayage. Des images de trame sont construites sur la base dimages balayant un trajet vers lavant, obtenues par le b
