<P>PROBLEM TO BE SOLVED: To acquire a fundus image effective for diagnosis, and specifically, to clarify the fundus region observed on a monitor in the fluorescent photography of the ocular fundus. <P>SOLUTION: The scanning laser optometric apparatus comprises an irradiation optical system with a light source for emitting laser light and a laser light scanning means for secondarily scanning the laser light on the ocular fundus; a light receiving optical system for receiving the reflection light of the laser light on the ocular fundus emitted from the irradiation optical system by a light receiving element; an image acquisition part for acquiring the fundus image based on the light receiving signal output from the light receiving element; and a display control means for displaying the fundus image acquired by the image acquisition part on the monitor. The image acquisition part of the scanning laser optometric apparatus has a differential circuit for acquiring the light receiving signal output from the light receiving element as a differential signal relative to the time axis as an analog signal, and forms the fundus image based on the differential signal output from the differential circuit. <P>COPYRIGHT: (C)2009,JPO&INPIT |
