摘要:
An ultra-wide ocular fundus imaging system (100), comprising a light source (10); an optical splitter (20); a scanning assembly (30); a curved reflector (40); a detection pinhole (50); and an imaging assembly (60). The scanning assembly (30) comprises a first scanning mirror (31) scanning in a first direction and a second scanning mirror (32) scanning in a second direction. Light emitted by the light source (10) passes through the optical splitter (20), and is respectively reflected by the first scanning mirror (31), the curved reflector (40), the second scanning mirror (32) and the curved reflector (40), and then enters the ocular fundus; the light that has entered the ocular fundus is reflected by the retina and then returns to the optical splitter (20) along the original path, and passes through the detection pinhole (50) and enters the imaging assembly (60). In comparison with the prior art, the ultra-wide ocular fundus imaging system (100) realizes ocular fundus imaging by total reflection, thus effectively avoiding ghost images resulting from imaging by using a lens module. Further, because the curvature of the curved reflector (40) changes gradually, the light reflected by the curved reflector (40) can enter the ocular fundus at a greater angle of incidence, thereby realizing imaging having a large field of view.La présente invention concerne un système d'imagerie de fond d'œil ultra-large (100), comprenant une source de lumière (10); un diviseur optique (20); un ensemble de balayage (30); un réflecteur incurvé (40); un trou d'épingle de détection (50); et un ensemble d'imagerie (60). L'ensemble de balayage (30) comprend un premier miroir de balayage (31) effectuant un balayage dans une première direction et un second miroir de balayage (32) effectuant un balayage dans une seconde direction. La lumière émise par la source de lumière (10) traverse le diviseur optique (20), et est respectivement réfléchie par le premier miroir de balayage (31), le réflecteur in
