摘要:
A fundus imaging system comprises: a reflection mirror that reflects a light beam incident on the reflection mirror after passing through a first focus so as to cause the light beam to pass through a second focus; a two-dimensional scanning unit that is disposed at a position that coincides with a position of the first focus of the reflection mirror and that reflects a light beam incident on the two-dimensional scanning unit so as to perform scanning with the light beam in two-dimensional directions; and a compensating unit that compensates for illuminance ununiformity of a light beam illuminating the retina, the illuminance ununiformity resulting from unevenness of a ratio of an angular change of a light beam emitted from the first focus during scanning of the two-dimensional scanning unit to an angular change of a light beam incident on the second focus resulting from being reflected by the reflection mirror.
